Asking $189.95 + $29.58 shipped. One seems to be a legit Con 2 but they applied the English on top. We already knew the trademark was in separate sections which were struck separately, but this is the first one like this I've seen. The other cymbal is an Italian made Zanchi Vibra. Different bells. Different hammering styles. The Vibra looks later (1950s) than the Con 2 (1930s). The earliest years for the Vibra series aren't that well pinned down. Pinksterboer (
The Cymbal Book p174) says "since the 1950s" and Luca Luciano (
Italian Vintage Drums and Cymbals, 1st Ed p136) gives 1947 as the year Zanchi got started as a separate entity from UFIP.
These images are reduced to meet the site size limits but I have all the originals at full size if anybody needs to see more detail.
