Jim,
When you get a chance can you take as many pictures of the bridge area and post them all and not try to make them into a collage, this is for two reasons. 1. it will give everyone a chance to look at what was done to their boats and see what is different between their boat and the Batfish and will allow them to post pictures of intrest for you to duplicate if possible and 2. It will give you a good before and after display when the project is done.
The Torsk's cigarette decks were cut off in the 50's and her step sail was installed, HOWEVER most of her bridge area to include around the periscope shears is still there so they maybe able to help with pictures and I am sure that Paul Farace and the COD can come up with some nice pictures becuase if I remember correctly his bridge area is all intact. I haven't been on the Pampanito's Bridge or the Bowfin's whom also are supposed to be intact and I was on the Conning Tower displays in Pearl Harbor and the one in San Diego in the '90s and they were all still together, granted that was 20 something years ago and without permission
A needle gun will be your best friend and your worst enemy at this point and you will need a large air compressor or getting your air banks back online to take up the slack for a small air compressor.. If I remember correcly there is a local reserve military base close by and see if they would like to donate their time chipping and painting. IF it is an Army Reserve Unit the soldiers can recieve a Volunteer Service Medal for volunteer work over 100 Documented hours and that is promotion points for the enlisted soldiers not to mention the pride that they get (or at least the pride that I got while volunteering) restoring something for future generations.
When you have the upper bridge hatch open the next time and you think about it take a green scrub pad and a small bucket of soapy water and clean the hatch seal and the seating surface on the hatch, it may not leak now but clean it and the seating surface so you don't have the leaks in the near future.
