Well, first of all that isn't "Einstecklaub", it is "Einschublaue" and the translation I can find is "insert blue". If I have it correct, Einschu" is insert and I'm pretty sure "blaue" is blue. I don't get it and there's probably a better translation as relates to firearms. I have an Einstecklauf in 22 LR for 16 bore barrels so I'm going to assume they're similar words for the same thing. I believe Bohler - Rasant is the type of steel the barrel is made from. I also think the best way to know precisely what it is chambered for is to make a chamber cast.
I would think if it is removable there should be some evidence at the breech end showing screws for wedges that affix the insert to the barrel. If the liner is permanent at the muzzle you should be able to see where the barrel was drilled and the line between the barrel and liner. Also, at the breech it should appear as a normal chamber.
The rest of the proofs are the usual German proofs for the 8 X 57R and the date of proof, which should be May of 1927.
Take that for what it's worth. I expect, and hope, Mike, raimey or Axel will be along to correct any of my errors.
A picture of the breech and muzzle would be of help.
