Hi, Pix!
While I have met and exchanged business cards with both Mr. Hasegawa and Mr. Tamiya, I would be hesitant to claim to "know" them! Mr. Tamiya did go out with us (Naniwa Sensha-tai, my club) after the Shizuoka Hobby Show for a few beers, though.
But I do work with Mr. Hirata at Tamiya, who is in charge of "Tamiya News" (I have an article and pictures in the December issue), so I'm sure I could show him some of your works. They are always interested in what's going on overseas with their products.
Gotta be Tamiya models, though!
Your Betty pic would knock their sox off for sure!
I always have to hunt for my sox after seeing your pix![:0]
