Does anyone have a link to Kynoch box codes. I used to have it but can't seem to find this info. I have a few boxes I'd like to know the manufacture dates. Thanks Scott.

Here you are alaska one. If you PM me with your email I can send a much better copy that also has scans of a couple of examples of Kynoch packets and their dates.

Thanks for your help on this. My 577 Nitros are 1964 and my 475 No2 are 1943 vintage. I'll send a PM. Regards Scott.
