Hello. I have become the lucky owner of some circa 1950-1960's era power tools, including one metal-bodied jigsaw with the only identifiable marking on it as "Sentry". As far as I can tell, there was no manufacturer by this name, nor can I find any other identifiable markings; however, I'm hoping someone may remember which hardware or department store may have manufactured tools under this name?
I'm looking for a replacement guide bearing for the jigsaw which is in otherwise good condition. I suppose I could have my favorite metalworker tap a guide hole in a stainless steel ball bearing, but I was hoping I might be able to buy one off the shelf if I could identify the saw's maker.
Any ideas?
