I don't remember the scale i beleive they 1:16, i layed a yard stick by them to give you an idea of the size.
I have had these cars along time, they are full of dust and the glue is drying out and they are falling apart. I think i have most if not all the pieces for them.
If interested please make me an offer.

Don "The Snake" Prudhommes sling shot dragster.

 

The 2nd is Ed "The Ace" McCulloch's 72 Demon funny car also in 1:16 scale, also have a 1:25 scale version that will go along with it.
Again they are both covered in dust and falling apart but i think most of the pieces are there.

 

I also have 2 other funny cars in 1:25 scale in the same condition, they are Jungle Jim Vega and a 70 Challenger namer Ram-Rod.
