Well Done, Make Everything! That is a fine little vice and like the tiny anvil on the back. Looks to have a substantial carrier for a small vice and adding the brass washers is something I do also. A trick I use on stuck flat heads is to heat it slightly and use a Hand Impact driver...hasn't failed me yet. Don't know if you have them in CN but they've been around for 50 years, and pretty reasonably priced. You could also save the table mount by creating a washer on the lathe with a loose clearance hole for the screw tip and then pein it over. That way you could use it if you need to.

Thanks for sharing the restoration with us. I love saving these types of tools...a shop can not have too many vices!
