Handy tool that I recently acquired, specially for side valves. I still have to try it out. Made by The Bridgeport HDW.Mfg.Co USA.

Yes indeed...Very useful...There are many versions of these older tools for side valves. I use a more 'recent' Snap On S.V. spring compressor I bought new about 30 years ago!...It's possible Snap On still make that one as there are plenty of 'flatheads' still running in the States....Ian
