i can scan in the rochester date / application system if you guys don't have it

also somewhere i have the ww stromberg numbers which i got off the net

if your at a swap meet or in a blokes shed and you don't want to piss him off by looking up numbers a quick reference is:

704xxxx small primarys big secondaries 1965-70
704xxxx 'normal primarys and secondaries 1971-1976
1705xxx 1976-1979
1708xxx 1979 up

basically if you find any of the early ones 1965-70, the matching number dudes will probably give you good money for them on ebay etc.
