I’m looking at a Miraphone 186 for sale, from the 70s. It sounds great, and it appears to be in excellent condition, but I noticed some spots on the leadpipe that appear to be red rot. Should this be a deal breaker? Opinions? Suggestions?

Any help is greatly appreciated.

Thank you for the viewpoint and the cleaning recommendation.

My 186 of similar vintage has similar spots on the lead pipe, I've had it chemically cleaned, and I try to clean it on a regular basis with dawn dishsoap and a brush. I've had other horns with these spots and never had one develop a hole. If it's only on the lead pipe, and you're getting a good price on it, what would it cost to replace the lead pipe if and when it develops a hole (which may never happen)? I personally if a liked the horn and the price was right wouldn't hesitate to buy it, and would use the red rot to try to negotiate the price down a little (it would help to know the cost of a newly installed Miraphone lead pipe going it) then ask the seller to split the cost of a new lead pipe.

I had to replace a lead pipe on a 1978 Miraphone 186. $ 900.00
