Keeping in mind the stadimeter and RAOBF were integrated with one another in real life, and were only present on very early attack periscopes, and were left over on type VIIA, IXA, early IIs etc. The C/2 Standsehrohr (big thick attack periscope with seat and pedals) did not have stadimeter or RAOBF, and that type of scope was found on VIIB, VIIC, IXB, IXC etc. etc. in other words the absolute majority of frontgoing U-boats.
