This is an Original complete kit I found and t' fins were cut out. So I have finished it all except t' paint detail. Aye aye! One thin' I always do is 'skin' t' fins with yellow file cabinet paper for strength/finish. Well, blow me down! I used Elmer's Carpenter glue brushed over t' fins and lay a cut out o' t' fins over top. Avast, me proud beauty! This is a Great thin' t' do for obvious reasons. Well, blow me down! They always come out smooth and strong, and last forever. Eliminates sandin' sealer and all that work. Avast! Hope you like it. Well, blow me down! Incl. is me other one I built in t' early 80s which is, also, an Original kit.
