As promised Darren here are the three Biddle Tachs I scored this week-end. All three will measure RPM or SFM. Left is 0-10K middle is 0-5K and right is 0-50K.

I have a couple of those tucked away somewhere. I believe they were made by Jagers.

Thanks for the pics Bill. I've not seen them like that before. Only the old steel graduated wheel type. Nice score.
I think i recognize the center one we used them in Simms engine lab on the dyno test. ours were made, or marketed, by Hasler, but the same even down to the case shape. One button to reset and the other to start the number count.when it stops you have the RPM spot on. Happy Days all noise-- heat--. asbestos lagging--carbon tetrachloride-- ETC,
Regards Brian. .
You are correct, the center one is a Hasler Bern. serial # 132022. The other two are Biddles.

Thanks for the memory jolt Bill, it just takes a photo like that to bring things flooding back
Days when you didnt care a dam just got on with the work that you loved doing.
Brian.
Brian -- I have often wondered how many stories like yours could be heard from the old tools I have collected over time.
