cut out the ports for the vents and used pieces of bronze guitar strings and a scrap piece of aluminium flashing to make the vent, and a scrap piece of flashing for the shield. I hadnt decided on the particular boat when putting the tower together, but now Ive decided on using U 571 as a guide. This model is being built with underwater photography in mind so precice detailing of one particular boat, is not really formost priority as is stand off underwater visuals of the Type of boat in action is the ultimate goal.
