This is an original Overland Allegany, no changes have been attempted. It is pretty damn good as is. A few nits: the motor is embarrassingly small, the same as one would find in an ordinary brass diesel; the crankpin screws are slotted rather then hex head; and the lubricator linkage is a single etched part - the Akane engine of the 1960's had a better linkage !
This Allegany has had some small detail upgrades. And the mechanism has been completely gone over to remove the tiniest of binds and friction. With a new flywheel and mechanism balancing this engine will really crawl, and climb a 40 degree grade !!
The trailing truck on this first run engine is from PFM, and existing detail has been tweaked, but more detail upgrades are in the works.
This very old Allegany, a sprung version, is undergoing quite a few upgrades.
OK it's not Brass, but this Allegany model is very good ! Could this be the 'new' brass from China ?
he biggest problem is the gap above the rear cylinders to allow the rear mechanism to articluate around its center to take small radius curves. Also it exhibits fine parting lines on the plastic castings. Only the smallest piping is cast on, larger pipes are seperate casting with some flash and bows, or wire pieces that need some adjustment. The lubricator linkage is excellent, as are the valve gear and rods. The painting and finishing is top rate with white tires and running board edges. Some aspects of this model are better then brass and some are worse, all-in-all a fine model.
