Found many threads with assumptions but no definite answers. I'm only curious cuz I just finished working on a 2215 that's champagne engraved and started searching only to come up with assumptions.
I found this old ad that goes into the subject but I can't substantiate anything: https://www.canuckaudiomart.com/det...hampagneengraved-with-wc-22-cabinet-serviced/
The one I worked on serial number is in the upper 1500's.
