I'm not certain that the "Antique" finish -- as it was called in Edison propaganda (not gun-metal, that seems to be a modern term) -- ever completely replaced the gold plated finish with the Official Laboratory Models.
I don't believe it did specifically in regard to the Chippendale Upright. I've documented some very late C 19s with both Antique, and Gold finishes.
Toward the end of production it seems the co. was using whatever they could find in inventory to fill orders.
It seems that you, Sean, and Bruce all have a variant finish I hadn't previously noted.
That surprises me a little, but then I haven't examined the W&M as intently as I have the Chippendale.
Would you say the burnished places on your horn is copper-like, and an exact match to the places exposed on your reproducer, or a different underlying color?
Best,
