Harmony guitar dating
The last new (old stock) American made acoustic finally was sold around 1980.
This was after I borrowed it to travel across country.
Along with manufactures like Kay and Regal, Harmony supplied a lot of instruments over the years.
I have had many other type of instruments made by Harmony.
There has been a lot written about the Harmony Guitar Company, but there isn't a lot of information on these guitars. Many a guitar student started on one of their student instruments.
The general quality of Harmony instruments was lacking the attention to detail that the more expensive guitar makers were able to achieve.
