Yo, Wartoy, The Scale Shipyard (Lee Upshaw) does build some nice hulls, I have heard nothing but good about him. He is currently trying to build a 32 scale Fleet boat, which he said was supposed to be out later this year. You did not state what scale you wanted your Balao in. Lee has several other scales available. SS 394 is a late Balao class boat, I think she may have carried two 5 inch guns, one forward , one aft. She was converted to a Fleet snorkel, So a later configuration would look similar to the Carbonero, A fleet boat bow with a step sail. She was built in Portsmouth so the limber hole pattern should be of a portsmouth boat not like an EB boat, plus other distinct charecteristics. Hope this helps, If I run across a picture of her I will let you know. Cheers, Go Arkansas.
