Marv,
It isn't a model plane but it is a model I scratch built from wood. The guillotine is on blocks in my basement and has been collecting dust for about ten years.
Soon I am going to contact some local museums and see about donating it.
I made about 400 custom knives over a 10 year period and built the guillotine for a big knife show here in Michigan. I only had it out of the house that one time because it is really big and hard to haul around. It may at first seem a strange thing to build but in the custom knife world it's a pretty cool piece.
I never cut anything with it because the blade is 1090 tool steel and I didn't want it to get dirty or rusty.
