I've put a German Luftwaffe Beer Stein up for opinions in the members valuation/discussion area; the stein (if authentic) is likely from the mid-late 1930s (photo below). The design has the following wording around the central motif, "Unteroffizier Corps der hoheren Stabe im Luftkries IV". A couple of experienced collectors advised me the spelling of "Corps" (vs. Korps) should be cause for concern, while a couple of other experienced collectors in another forum told me the spelling of "Corps" (with a "C") is not unheard of for the period.
I'd be interested to hear other opinions on the spelling of Corps vs. Korps in the context of a LW-themed beer stein from the mid-late 1930s.
Thanks!
