I have seen one of these before but I thought I'd share the example I just picked up from an antique store in the burbs.

the box is in very good condition:



Side labeled "1" is the old rock italian razor hone 7" x 1 1/8" and an estimate of about 1/8" thick:



Side "2" is just wood with red strop dressing on it:


Side "3" is cushioned leather with black dressing


Side "4" is cushioned leather but I can't tell if it's plain or has some sort of abrasive in it.



I saw another owner of one of these removed the stone and put it in it's own holder but I think the leather is in reparable shape, so I may just try to clean those sides up and keep this whole thing intact.
