And yet again Wolfgang comes up w/ another fantastic find:

Alleinige Verwertung
Der Gewehrlauf-Marke
R.O.M.(Where the O is the Ehrhardt Trademark)
Radial-Stahl-Rohr-Extra Qual
(Patent Ehrhardt)

Verbiage from a Postkard from 1913.

Which notes that Meffert is the Sole outlet for Ehrhardt patented steel tubes.

Cheers,
