Thanks papadan! I'll keep your offer in mind, which with my memory will be 2-3 days.
Here's what I've learned so far - mostly from this you-tube vid -
https://www.youtube.com/watch?v=dnbtMNqaRAMBelzer existed as a company from 1884 to 2003 - the name is still being used for tools made in Brazil.
In 1970 Belzer merged with Dowidat.
In 1988 Bahco took over Belzer-Dowidat.
In 1991 Sandvik bought Bahco.
In 1999 Snap On bought the saws and tools business from Sandvik.
I guess at this point my biggest question is, when did they make this set of tools?
