Schreiber Clamps - Can You Help Me?

I am looking for some over center, cushioned faced spring type clamps - the name Schreiber is stamped on the handle.

When I got them some 25 odd years ago, I think I remember they were classified as "laboratory" clamps, and used for pinching tubing to shutoff flow.

I use them as part of my rudder control lock system and need another set for the airplane I am currently building.

If anyone knows how these may be acquired now, I would appreciate your input.

Thanks all, in advance.

It's not quite the same thing but I see a lot of clips of a similar design by searching "tarp clips"

Thx - I'll give that a try.
