I wasn't sure whether you were talking about model numbers or serial numbers when you first posted since you said "cipher". There is really no cipher necessary for a model number, it just is what it is.
To my knowledge, this model of Kimberly had no model number other than perhaps a generic ET-400 designation which means electric guitar with 4 pickups. This model was introduced around 1969 and lasted until about 1974. The only differences across this time was the floral pattern on the pickguard but I've never been able to associate this variation with model year since floral models appear in all years of production. Look in the Japanese Guitar Gallery under "apollo greenburst solidbody guitar ca. 1969" to see two variations in pickguard decoration.
This Kimberly was sold through Department Stores and Electronics Suppliers like Lafayette where model numbers were not used in the descriptions. It was advertized as a "Deluxe 4-pickup Solid body Electric Guitar".
If you are looking for a serial number, it doesn't exist.
BTW, the bridge on yours looks like a replacement. It's probably better quality than the original.Statistics: Posted by VintAxe — Mon Oct 03, 2011 5:09 pm
