The 505 photo in prior post is the kit I bought at the Museum. Approximately 1/200 scale but nothing actually printed anywhere. No manufacturer on box but instruction sheet read Revell. It looks pretty close to the actual boat.
The 505 kit I have to build yet is 1/144, also Revell, 1988 kit but not correct! The hull and wintergarden are like VII-C. So I'll build it out as another number.
