I’ll try to address some of the queries.
An oval hole F model (2 or 4) is going to run somewhere above 3000 dollars in the US, more likely 5 & up. They haven’t been made for about 60 years, & are real gems.
All new Gibson’s are made in Nashville; in the 80’s & 90’s many were made in Montana, after Gibson bought out Flatiron, which it is said they’re about to use on an Asian import brand, as they have done with the once competitive & formerly prestigious Epiphone brand.
There are many builders who will make an instrument that will compare favorably. or better, to a Gibson for about the same money or a little less, a few for substantially less, & the top few for More (Monteleone, Gilchrist, Nugget, or Dudenbostel, for instance, will run 25,000 or more, slightly more than Gibson’s DMM top of the line).
The F9 seems to be a great buy, & should be right around 2900 to just over 3000 in the US.
