I have the Takom 1/350 kit of the ABSD-1. ASBD-7 was rebuilt into AFDB-7 to service Polaris subs at Holy Loch. The kit has plain walls with nothing outboard of the walls, but at Holy Loch the dock has an added framework and widened decks on top of the walls. This Navsource photo shows them:
Are there any plans that show the added framework and decks?
Sorry that I missed this posting, just like many others I (apparently) wasn't drawn in by the title. Fortunate that you posted it later on in the 41 for freedom thread!
