I just added the advert , I believe this is a cyrano
I believe your right, I thought the black on the photos was reflection...Cyrano it is.
Cyrano is correct with the black enamel corners.
Agree with Cyrano ID - nice one too.
Thanks again
agree with Tickers observation of the mis-struck 0
Nice find, a Diamond in the rough.
Agreed, Post it. Nice to see one with the enamel intact.
Great , thanks
