replacement barrel?
 

I have a 1912 Erfurt that is matching except the barrel. The barrel has the same imperial eagle (but with a very small marking something like a t with a 0 acroww its vertical staff to its right)as the receiver does right next to it. But there is no serial number on the bottom as my other lugers have. It has a reference mark with 2,28 by it. There is also a single 3 just ahead of that. On the left rear of the barrel near the top is and eagle or crown (its very small and hard to make out over 33. Is this a replacement barrel? jl

JL, The E/33 sounds like a Simson proof. TH

Thanks,is it possible to date when it was done? JL

John, if it is a eagle 33, then yes, but pictures of these marks, and each side of the gun would help very much...
