I help maintain a list of orphan engines and frames on another /2 website. Here's the page:
A situation has come up where a widow is trying to deal with some old BMW parts in her house. I was alerted to a couple of bare cases that could be salvaged but it sounds like I need to find someone who can take possession of the cases before they go to a recycler...that way we can figure out how to care for them in a longer term fashion and put the engine numbers on the website. It's a long shot finding a pairing, but over the years, at least 5 engines/frames have been repaired...a bit of a success story.
If anyone has some recommendations of who might be willing to start this process, let me know. I don't know all the particulars, but will find out.
