The biggest ones I have now are the 1/48 B17 and 1/48 PBY / OA Catalina. Then I have a bunch of 1/72's, not a lot but for the space I have it cant compare. I could say I have about 10 kits, maybe 2 plus or less, not going to count.
Why doesnt your brother go active on here and share his work? (Or has he?)
