Haven't logged on in like 5 months and can see the Love is still going strong here
Back on topic, it is very possible that the serial numbers were broad for any item coming out of the plant. When referenced with the model # then Gilson would know when it was made from their internal records. (This is just a theory)
They did not make 100k 525's that is pretty certain.
As far as when you define a "craze" starting and ending?
Usually anything that started on the west coast is past it's prime once the East Coast catches on. LOL
Statistically it would be at it's zenith when the largest amount of manufacturers were providing and selling thru their yearly inventory and ends when the makers go bankrupt and consolidation occurs.
One only needs to read the long story of the Lil' Indian to get a good grip on when those dates occurred.
Carry on
