Copper Tube Needed For Burrell Boiler

[Phil Procter]

This is for a 1½" scale Burrell SCC traction engine boiler. I am having a real problem trying to locate this size.

I am looking for a length of 3.5" OD seamless Copper tube either 13 or 10 gauge, I need a piece about 8.5" long.

So as not to waste anybody's time, I do know I can get 16 gauge but that is too thin for this job. I also know I can get 3.75" diameter, but that is too big.

Thanks
Phil
