I once saw about 4 variations of 1870 ek1 for sale on a German auction site. All looked incredible with different variations of pinback and maker. The prices were about 300-500 Eur, and they were all listed as reproduction. That really did it for me as I could not tell the difference between these and the ones in The Iron Time.

Rod- maybe you should post in the language forum. Or maybe query 'Wotan' directly as he may know.
