I have a five string replacement bridge of unknown origin available for sale. It is die-cast, chrome, measurements are 3 7/8" x 2 1/4", 11/16" string spacing with about an overall spacing between low and high strings 2 13/16". I don't have a scale to accurately weigh it, but it is substantially heavier than a comparable stamped metal bridge. $20 shipped and it's yours. Paypal accepted.
