Vintage Schick Prototypes/test units. Do I want them?

I own several Schick Magazine Repeating razors. Am fascinated with the design and mechanism. I spotted a few early Schicks for sale, some I have never seen before. Also there was a repeater that was obviously a prototype. It has the usual handle but an unfinished pivoting head that seems to made out of sheet metal and rivets. I also spotted one with a different design folding head in the lot.

I know Gillette prototypes are valued. Is there any collector interest in prototype or test model Schick razors?

There is an absolute great interest in any prototype, pre production, and limited production razors of anything from Schick or Gillette (or anybody else). Got pics?

No pics. My phone was dead. I will have to buy the whole box full the seller says and there are many plain jane familiar ones in there. I'll post pics if I can work out a price with the seller.

Here I go down another rabbit hole.

i think you got me started on the Schick repeating razors, and now i have several from type a to c and use them all. i will be watching for the pictures if you end up getting them.
