Cornwall Year Manufactured - 30X-###

Recommended Posts

Im looking at a part of consecutive Cornwalls with the serial number stamped into the wood.

 

Starts with 30X then three digit number.

 

Does anyone have a ballpark year of manufacture.

 

Waiting for more pics to review.

 

Thanks!

1981-82 timeframe is when they were built...cabs could have actually been BUILT in late 81 and hit final assembly in early 82.  Things sometimes happened that way, back then, especially during rush periods like around the Christmas/New Years holidays...before and for a few weeks afterwards...labels were completed and installed at the final assembly area...where drivers, horn lenses and crossovers were installed...right before testing and packing, which was also done in the same general area.  All of us ended up over in that area at one time or another assisting getting speakers completed, and boxed up  for shipping and stacked ...especially during rush periods when there was no more room to put new-builds from the cabinet dept... waiting for sanding.  Sanding Dep't, finish Dep't, and shipping Dep't were all "choke points" for products...waiting to go to the next dep't or out the doors...Everybody ended up becoming a "jack of all trades" within the plant, in those days sooner or later!  I sincerely doubt that the becoming a "jack of all trades" thing has ever really ended at the Hope plant, myself...especially so for the builders in the cabinet shop!  AVAILABLE FLOOR-SPACE was ALWAYS the biggest issue during rush periods

Thanks!  What would be the constuction of the Cornwall cabinets in 1981 / 82.  Plywood, Burtch or other? 

That depends on the model.  I most likely built them.  What is the model?  It is written on the labels!  If CB(X) models, then the panels for the cabinet were custom-laid Georgia-Pacific 7-ply plywood.  If they were veneered in fine veneers, then the substrate under the veneer is poplar-lumber-core plywood....also custom laid up and finely-veneered by Georgia-Pacific...those will have mitered corners where the box panels meet each other.  The motor-board was still made from that birch plywood though.
