Thank you Hans, I picked it up in Covina Ca in 2003. The best 6 string I’ve owned. I like playing in lower tunings. I’ve got her in
C Hejira. Enough said. Was this build from pieces cut at the old factory? Other than some hairline cracks in parts of the neck binding and a couple whisky bumps from on and off stage, it’s a beauty, both sonically and optically!
I didn't think the (early) Corona F50 used Westerly parts, as it was a "re-issue", replacing the Westerly JF65, and I don't think the JF65 was a simple re-name of the F50, and I suspect the Corona F50 had some subtle spec differences from a JF65. But it's "possible".
I do think they used some Westerly-built necks on the early Corona JF30, D40, D40ce, D50ce, and F47Rce, because those models started in Corona with Westerly-style "snake-head" headstocks and gained the wider traditional "paddle" style headstocks later on in the case of the D40 and JF30. The cutaway electrics used the same Fishmans used in Westerly.
This is just guesswork on my part. Hans Moust has confirmed some "kits" were sent to Corona so that their novice (to flattops) luthiers could practice on 'em. Never saw anything stating those pieces actually got put into retail sale and I'd doubt it very much.
But the issue of possibly using perfectly good sub-assemblies like finished necks from Westerly in Corona builds strikes me as a different issue, more akin to the transfer of the woodstocks and other raw materials that were perfectly usable.
I got a Corona D40 in early '04. Surprised me at first because it wasn't a "cannon" the way I was expecting. Patience was rewarded though and now it might be my favorite voiced guitar. For sure it's made the best sounds I've ever recorded.
