Thanks for the link to the models WMachine, but I still haven't found the specs for the Kluson tuners model with dot markers.
It’s no wonder that Gibson almost went bankrupt.I'm not sure why you are confused. They are different models. You have about 5 years of production to look thru. There are lots of models that are never on the Gibson site. Dealer order models, made for overseas models and such are never on the site. Can only suggest googling finding ones that are/were for sale for specs and identification.
Read up on it. That has nothing to do with the bankruptcy. It was not the guitar business that sunk them.It’s no wonder that Gibson almost went bankrupt.
