dual cuts on inside of cylinder plus 2 extra smaller cuts on each side. sorry its not a good inside shot. #4 ??

anyone seen incorrectly marked cylinders before? I have seen several unmarked cylinders. Identified by internal cuts on inside of cylinder only. The guide on CEF for cylinders is very good and accurate as far as I know.

As far as I know, all #2 cylinders were single by-pass, fitted to Babe & Golden Bees.

Rod: All #2 cylinders? I have a bunch of #2 cylinders I purchased in bulk from the "cox boys", ESP, or cocengines.ca and they look more like #4 cylinder with dual thin slits.
Someone please explain this to me?

I do think we're seeing a lot of hybrid cylinders out there, either post-Cox modifications or late Estes "couldn't be bothered" cylinders that were not so closely scrutinized.
"Traditionally", #2 cylinders were single bypass.
