So, after reading about your super nice refurb on your Prentiss vise, I got curious and went out to Grandpa’s old shop to take a closer look at his Prentiss vise. I was shocked to see that it is also a Prentiss No. 92 … same as yours … well, not really the same, … your’s looks great compared to Grandpa’s. I think his old vise has led a hard life.
I sure appears that the two vises are very similar so the “early 1930s” estimate may be a little off. Perhaps these are from the 1920s since that is about when Grandpa built his garage/shop.
Now I’ve got another project to add to my list! I sure hope I don’t run out of years before I run out of projects!
