rex desilets posted:The PRR M-1 boiler is the I-1 boiler with a substantially lengthened combustion chamber. I *suppose* you could graft two AF K-5 boilers together and develop the Belpaire contour with a ton of work and/or massive applications of Bond-O.If there is a Berkshire in S, it could serve as the chassis for an M-1.
There is a Berk in S, but either the River Raisin one, which would be too costly to junk for a chassis, or the Lionel one, which is also a bit costly to cannibalize. Are there more? But if someone out there has a Lionel one that has fried electronics, or has suffered a high speed meet with a concrete floor, I'd take a "bash" at it. I remember seeing a fellow at an S event who had a number of K5 boilers for sale, already striped of paint. Sheesh! I REALLY don't need another project!
