I remember these Guillow's models being a quarter. Walk in to a hobby store and they're close to twenty dollars. OUCH! I feel real old about now. DOUBLE OUCH!!!
I think the Spitfire is the only model in their line up I never built. Had a lot of fun building these models and seeing your build filled me with memories of saw dust, tissue paper and dope. I won't even mention the smell of Ambrose glue. The best flying model was the Bird Dog. The balsa was very light and the wing loading made for a fun flier.
There was another company that made the same sized models but instead of pop-out pieces you had to cut all the parts out. I enjoyed that too, unless the balsa was poor quality and split along the grain too easily. I can't remember the name of the company but the added cutting made for an interesting approach to building.
Ahhhhhhh. Memories. Nice job.
