Good vintage condition - WORKS - Tested on sheet metal, and 100% guaranteed. I have not modified or refurbished this tool in any way.Small stamped label on top of handle reads'MECH ENG. Gear box is well lubricated with what looks to be a PTFE (Teflon) based grease.
It could be a lithium-base grease, but I don't think so. The high price reflects the fact that I could find no information about this tool or tool company through Google. Label reads as follows (underlined information was added by me, not written on the tool).
