I just got to wondering about these things, so I thought I'd ask.

When was the #5-4 first made?

When was it added to the catalog?

Was it always made from 3/16" stock?

Only 3/16", or was 1/4" used too (like the 4" Stanaback Special)?

Was it ever available with a leather handle? Why not now?

Anyone have photos of old ones? Please post them if you do!

Thanks!
