Good to see. I want to start doing that, but the most I've completed (that worked) has been a few venturis & needle assemblies, and little bits and bobs of model hardware (it's amazing how easy it is to spend half an hour making a hand-machined part to replace something that you'd by for $1.29 from Brodak's -- if you could wait for it to show up).
It's nice to see build logs from someone who can actually make it all work -- please keep posting pictures.
Reputedly, someone's picked up Roger's castings -- Hemingway? If you could figure out who, and if they have any spares, and if you sweet-talked them enough, you may be able to get a replacement*. I know Roger had a rep for replacing castings with defects, no questions asked.
* That's a lot of 'if's
