This is a very rare vintage Standard Self Inker / Office Desk Hand Ink Stamp. The handle looks like aluminum??and the rest looks to be made out of pewter?? It is unmarked and measures approx 10"x4"x3.25". Comes with a rubber stamp pad (see last picture....I have reversed the picture so you can see what it says). Overall in very good condition with some minor surface rust that can probably be buffed out. Fully functional & great addition to your collection. Thanks!
