Shot in the dark, here, but I know a lot of you play...
I have a Japanese hollowbody I picked up on ebay years ago for $75. It was incomplete and a little beat up, but it kinda spoke to me and it came with an interesting story - I took a chance on it. And then I quickly lost interest and put it in the closet for several years.
I dug it out the other day and decided I would take a shot at getting it back in playing order. Based on the internets, it is a Greco ES920, which were built in 68 and 69. Here is a complete example* (http://www.ebay.ca/itm/120748729858) Mine is missing pretty much the whole bridge assembly - it only came with the tailpiece. From what I can tell it doesn't share any parts with any of the other lawsuit-era makers, so I am expecting these will be difficult to track down. I thought about replacing the whole shebang, but the neck is fairly narrow, and I am not sure how well retrofitting will work. I took some measurements and I couldn't find a Bigsby-style setup that was close enough for me to take a chance on.
Does anyone have a good source for rare or oddball parts? I have tried all the major outlets, and I have only found complete models - I guess I could buy a working one, but I kinda want to get this guitar put back together.
I've had good luck with some odball bits from an outfit in Lansing Michigan called Elderly Instruments - http://www.elderly.com/ (http://www.elderly.com/) - give them a call (and if you're ever in Lansing, be sure to stop by - room after room of drool-worthy vintage & new guitars, violins & other instruments)
Also, if you've got a local luthier/guitar doctor, he/she might be able to fabricate something custom for a surprisingly reasonable price.
Elderly is a great source !!
Stewart Macdonald is another good one. A lot of the repair places get their parts from them. http://www.stewmac.com/ (http://www.stewmac.com/)
And then there os Warmoth, depending on what you need. http://www.warmoth.com/ (http://www.warmoth.com/)
Based on that eBay example, and your talk of a narrow neck, I'd say one of these (http://www.stewmac.com/shop/Bridges,_tailpieces/Archtop_guitar_bridges/Tune-o-matic_Bridge_For_Archtop_Guitar.html?tab=Specs#details) with one of these (http://www.stewmac.com/shop/Bridges,_tailpieces/Electric_guitar,_Tune-o-matic_bridges/Locking_Roller_Bridge.html) mounted to it should hook you up quite nicely.
Well...
Any word?
