Franklin 145

I've dug out an old 1930 Franklin sidedraft engine, and its missing several parts. Starter and valve covers seem like the toughest missing bits to fabricate. Any leads? Could also use one intake rod / housing, a couple valve retainer clips. Or just an entire donor engine. I also have an old box of parts, including a complete Atwater Kent 5970 Generator for series 10 if that might sweeten the pot for someone.
