Greetings from Finland!
I’m unable to identify the Premier kit shown in attached photo.
The salesman told, that the kit is full mahogany Premier 401 Byron from 1970, but this kind of kit doesn’t exist in any catalogue.
The serial numbers are: 22” bd 8718, 12” tt 4958, 14” tt 5395 and 16” ft 14746.
Can anybody help me?
