Usable condition item with rust area on the header as expected for a 40 year old part, it DOES have some gauged area as in pictures and ALSO when you shake it it HAS some metal rattle from inside. Probably some of the inner layer mess has been detached. It was on a runing bike that performed normaly before i parted it out.
PLEASE ASK FOR MORE PICS IF YOU ARE REALLY INTERESTED. Check with your Yamy dealer or diagrams.I have many parts n bits from this old smoker! Please ask any Qs all will be answered....
