That's about as likely as finding a chicken with lips! I helped a high school classmate install a Jasper 216 in 1965, and that was one of the last times I've ever seen one. Jasper and some of the other professional rebuilders stopped building Babbit-rod engines at least 40 years ago, mostly because of lack of demand. An oldtime machine shop near my home scrapped dozens of reconditioned Babbit rods several years ago, because they hadn't sold one in years.
