Tony, I am confused about your Hagstrom made Kent. I thought all Kent guitars were Japanese. Hagstrom was a Swedish company. My 3rd guitar was a Hagstrom III, and I can tell you there is no comparison as to the quality. Kent was terrible. Since you are a collector, I have my first guitar, A Danelectro U body. Have no idea exactly how old it is. Bought used in 63 or 64. What I've learned is that they were probably made in 56 to 58.
