I'm looking at a Gunson one. Anyone have any recommendations? It's not going to get masses of use.

I had brilliant one many years ago ( mid 70's ) but when I emigrated to Australia some time later it went missing during it's trip here - some F@#$%^g Customs worker or similar decided they needed it & other items ..more than I did ! I recall it was then an expensive unit made by a Company called "Sun" & it had the ability of variable degree settings, which then was rare ...so you could mess about & set your timing degrees fully advanced... to exactly what ever you wanted by just setting the degree reader dial on the strobe itself... to say 37 degrees fully advanced & all you had to do was run up the motor to just above the fully advanced revs point & then adjust your timing back plate as usual until until the corrosponding 2 marks lined up & lock it off there ...that was it 37 degrees BTC ...or whatever degrees you wanted. This is of course assuming that your OEM Adv & Ret'd marks themselves are accurately & correct stamped... which 99% of people take as Gospel ....to be 100% accurate of course.......you'd have to, find "True TDC" first by using a Piston Stopper and a degree disc , then you could manually check your Adv & Rt'd unit marks are accurately stamped & spot on ( likely not as = mass produced items ) then alter them accordingly ....then use the Strobe knowing it's effectively dialled in and therefor truely accurate....'sort of defeats the object I know' ..haha . Now we are into the realms of Blue Printing , where we all end up OCD & Anal !!!!!!
