Machining these would be expensive, what about having 1 recast in brass mix
that's what mine is, fortunately I came across 1by chance while building the car
have had no issues with it at all, they only issue is you would need to get a mold made.
there is the possibly of a market for them as this is definitely a weak point, you need to find a good caster or even artists the work in brass / bronze could do that, use the lost wax process as sand casting will require a lot of filing to get clean crisp lines
If I am correct the 1930 is the same
