Does anyone know the difference % wise of frames made from Accles & Pollack Cro Mo, Reynolds HM, Reynolds 531 plain, & Reynolds 531 butted, or cheap seamed carbon steel please.
Trying to establish as to whether you can identify what type of tubing might have been used on old 50's,60's frames when there are no markings left ?
Are there any other ways of identifying them other than a tame metallurgist !
Many Thanks
