Correct. I measured a couple of sets & they are integer cm like say 65cm and of course it could well vary with calibre but should be integer cm. So, in my mind what this does is again point to say a gesteck or parts kit that was in English units? Belgian maybe, which could have easily rolled their tubes to integer English units of length. Too, I have read that Wilhem Förster did source the Brits but that is unsubstantiated for now.

Cheers,
