Unfortunately there should be one taken by Schroeder on the other camera, will look again this evening. Hmm, seems Oleks also escaped from the group photos.

I'm fairly certain I took one and since I failed to smuggle the camera back into my own car you should still be in possession of it.:O:

Really a bunch of nice guys!

What? After all I've done to you???:o
Got to try harder next time then.:shifty:

fun terminated:O:

I still have fond memories of the discussions we have had on TS in previous years and always found you to be friendly and polite.

I remember...you asked me about U-boot stuff and I sent you a "NewView" file for IL-2....I'm afraid my hearing has gone further south since then....:88)

How many of those shirts does Neal have? :D:O:

He better have a few in a larger size!
He's starting to over whelm the old one!
:haha:

OK. 10 days in the brig?
:hmmm:
:03:

I suppose, but why would we want to put Neal in the brig?

To keep him from the 'All You Can Eat' places?
:haha:

Btw: Has anyone yet recognized Neal's similarity to Mel Gibson? :haha:

I do believe that was brought up at the 2008 Subsim meet in his house.
I do have to say Neal is ageing much better then Mel.
:D

Hello again,
some more photos, the rest can be viewed or downloaded via the dropbox link at the end.

Once more the observation perisope down in the control room, we were wondering why there are two oculars.. anyone?

The "Weihnachtsbaum", or christmas tree. The black shaft at the left turns the antenna, when extended.

Currently talking with Neal and I told him you look a little like u_crank :03:

I'm regretting not having done that now.

I wish you had been there, brother. I think we would still be there now if you had.

Too right mate, too right :03:

In the control room of the U 995 (located in the Laboe type VIIC U-Boat converted to museum-ship) is installed the type ASR C/13 (Angriff-Sehrohr) periscope. This is post-war periscope designed by Zeiss, based on the war-time type ASR C/6 periscope, which was designed for type XXIII U-Boats. This periscope consisted of the ocular box of type NLSR C/9 night periscope and periscope head of the type StaS C/2 attack periscope. The ocular box of the type NLSR C/9 night periscope was fitted with additional optical system (kind of telescope), which made possible reading of the bearing while looking through the periscope. The bearing scale was visible in the upper part of the view field. This optical system consisted of prisms and lens, and transmitted the view of the bearing scale through the slit in the periscope collar to the ocular box interior. Type ASR C/13 periscope which can be seen in the U 995 control room comes most likely from the U-Hai or U-Hecht (ex U 2365 and U 2367 respectively) and was installed on U 995 in the time when (most likely) she was converted to the museum-ship (during her service in the Royal Norwegian Navy as KMN Kaura, in the control room was installed the original type NLSR C/9 periscope).
The ocular box of the type ASR C/13 periscope is simplified version of the type NLSR C/9 periscope ocular box. It is slightly smaller, however the layout of the oculars, knobs and levers is the same. The ocular box is not fitted with the optical system for showing the bearing scale in the view field (the system was probably abandoned to make the manufacture simpler, faster and cheaper). The current periscope bearing is indicated by indication line, engraved on the periscope tube. It points the current bearing at the fixed azimuth circle. That's why type ASR C/9 periscope is fitted with only one azimuth circle, with 180° mark directed toward to the bow (please note, that azimuth circle in the U 995 control room is not properly set relative to the U-Boat longitudinal line). Over the fixed azimuth circle, the deflection angle ring is located, which is used in the same way as in case of previously described periscopes.

This is the best thread... wish I'd been there too :) Maybe next time. Nice to finally see your picture, Catfish :up: (and Schroeder)

^ i will translate it as soon as i get to my Enigma at home :03:
Has it the 4-cylinder naval array? :hmmm:
Bl!tzkrieg is unbelievable, in a positive way :haha::up:

From the side i posted, eh? Well i read it, but i still thought it was something else. But it isn't :haha:
I thought there was a kind of rectangular "box" over both oculars, seems i looked at the wrong side :o :huh: :oops: :/\\!! :dead:
Thanks for posting this once more, so Einar and Oscar will finally know what it is for.

Does Dan "Elanaiba" read this, too? I am trying to find out where the switches for the clutches of the electric engines are, we both did not find it. But we will.

German boats were quite simple and not Diesel-electric, like the US ones.
So the Diesels had to be installed inline with the propshafts, not scattered all over the place and just feeding the batteries, driving the boat.

Basically it is like with all old "Tauchboote" with Diesel propulsion, you use the Diesel engines for running surfaced, and the electric ones for running submerged. You charge the batteries with the Diesels.
In the 'normal' german boats the electric engines also served as generators, so you did not need additional dynamoes or alternators (not in the IXd1/2/42 and XXI/XXIII types though, they were already different).

You could also use all kinds of combinations. The whole layout is quite simple, but versatile and practical, there are clutches to use and combine all components independently:

- You could run the Diesels alone, coupled straight through the propshafts for moving the boat surfaced (or submerged with a snorkel)
- ^ coupling the electric engines in generator mode to the propshafts driven by the Diesels, thus charging the batteries but reducing overall speed a bit
- Run both Diesels and couple the electric engines on the propshafts driving them directly together with the Diesels, adding a few knots to overall speed, but draining the batteries fast
- Uncouple the rear propshafts with the propellers, switch electric engines to generator mode and couple them to the parts of the propshafts driven by the Diesels (dead in the water then)
- Use one Diesel to drive the boat and the other for charging
- Use one Diesel for running, while maintining/repairing the other Diesel, this way you can either:
a) charge the batteries by driving the electric engines in generator mode coupled to the propshaft driven by the one Diesel
b) charge the batteries by coupling the electric engine in generator mode, of the stopped Diesel side, to the moving propshaft, driven by the propeller moving through the water, Diesel clutch on this side is then uncoupled
or both a) and b)

Does that make sense? Anyway we were looking where all the switches and clutches were :yep:
