this may be too crazy, but here goes:
Some engineering students receive a emblem called a "bent" that is meant to resemble a bridge truss. I remember it being sand cast in bronze, and you had to polish it. If you contact a university's Engineering College you could ask where they source them. Or you could contact Tau Beta Pi, the engineering society. Not sure why you want sand cast - the finish is usually a bit coarse compared to lost wax. Some jewelers use lost wax. Additive manufacturing ("3D printing") is another possibility using the sintered metal process. Others here have much more experience with it than I.

For many years an excellent source for such parts was Gere Verdone who reproduced them in stainless steel via the lost wax method. He also had a very significant inventory of standard coachwork hardware. Gere's gone now but as I recall his business and inventory was purchased and continues. Anyone recall the details.....?

Many years ago someone here in Australia was casting 1920's Packard door handles and window winders in Pewter. The results were very good. I was concerned they might not be strong enough for handles but they were fine. The source has long gone but the reason for mentioning this is that the supplier said that Pewter with its very low melting point was easier to cast than say brass. just my 2 cents worth.

Hi David,
My limited research has led to a similar conclusion: pewter casting, using a silicone rubber molding process shows the most promise of retaining the detail of the original piece while providing enough durability to survive. I have a lead on a pewter casting artist here in California who hopefully doesn't charge exorbitantly. Thanks for the input. John

If it can be disassembled at the pivot, it's right up Crin's alley. Unfortunately I've written to him a couple times about another project and have not gotten any response so he's either very busy of he doesn't check his junk mail folder.

I am not an expert, but the silicone method is what I was thinking when I saw this. Make a silicone master inside a plastic foundation, fill the master with slow curing epoxy resin, use the resin master to make a clay/plaster casting inside a wooden foundation.

I have the same hardware for my 640 Club Sedan. It all needs to be plated. Was it Nickle or Chrome in the interior.
