Are these Quincy pipes?

[Heliarc]

I was hoping that someone might be able to verify something for me. I have attached two pictures of exhaust pipes for an A or B deflector Mercury. If my fading memory serves me correctly, these are Quincy Welding pipes from the early 60s. They are steel pipes and there are two water relief holes at the top of the plate & two in the front of the plate. All four holes are drilled on an angle to spray water on the pipes and elbows. Any input would be greatly appreciated.

I bought these pipes just the other day. While they are pretty old, there is no evidence that they were ever used - not even bolted to an engine. I am glad to have found them. Quincy pipes?


Thank you,
