bdb,
I did not see any indication of the barrels having been removed, at least not in the photos. Proof marks, if any, will be on the bottom of the barrels, which must be removed to see( and photograph) proof marks. Proof marks, if any, will provide helpful information, but to definitively ID the cartridge you should follow Sharps 45-90 and montenegrin's advice. A sketch with dimensions to the closest thousandths of an inch will be most helpful. This level of precision in dimensions is common with gunsmiths and handloaders, so don't be afraid of it. Mehlis is an area near Suhl and has a Proof house nearby( Zella-Mehlis).
