Hi. I'm trying to date a pair of Zildjians. One is approx 15 & 1/8", 950g with small centre hole. the other is approx 14 & 15/16", 975g with "modern" centre hole. From what I have seen online, the stamps appear to be late 1950s. Could anyone confirm this for me please ? Also, there is a suggestion from the owner (the widow of an ex-pro dance band drummer) that they might be late 1940s - is this possible with these stamps ? Many thanks in advance for any info ! Having trouble uploading pics so here's a link to them...
