G'day Ed,
Worst case I think that an hour with some flat bar, an oxy and a beer in the shed would have that licked. Not a difficult piece to replicate (particularly as you have the other to copy) and also as it is screwed in and not riveted. Do you not have a local metal shop in your area, if you do not have the facilities at home? I can see it being a $50 job. (chrome an extra $50) Regards. Q
