Product Description
An HO scale kit to make an early iron car known as a 'pot hopper.' These cars were favored by the Baltimore & Ohio, Cumberland & Pennsylvania and other American coal hauling lines from the 1840s to 1900. This particular model is of the ten ton version from prior to 1860 as it appears in photos taken at Martinsburg, Va. with corrections inferred from other Civil War era photographs and diagrams in J H White Jr's American Railroad Freight Car. Cars of this design were used well into the 1870s or later. Along with the chassis and pots is included two types of brakewheels (facing the side or to the rear), two sizes of turnbuckles for the internal drawbar, and optional link and pin couplers.
The brakewheel parts are positioned by a tiny hole at the base of the stantion that fits over the appropriate bracket bolt. There are small holes through the pots for two lengths of 0.015" wire used for the drawbar, with a turnbuckle connecting them in the center. The outer ends fit in the locator holes behind the coupler. The separate couplers are for if a more conventional height is desired, and fit in holes started in the correct position for Kadee coupler boxes (which will need modification to fit). There's plenty of room for N scale MT couplers.
In addition to wire for the drawbar (admittedly optional and covered by a load anyway), this kit requires 33" wheelsets with 0.990" to 1.000" length axles. Wheelsets up to 1.010" such as a standard Kadee will fit but are hard to remove without risk of fracturing a sideframe. A 0.990" is loose but gives a little slop for sharper curves, so you could use them for the inner wheels and 1" for the outer and be fine. With all four axles 1.000" the car will manage a 16" radius, so this is what I use. Photo shows metal wheelsets from Reboxx (#33-1-1.000).

Clean with alcohol or use Bestine rubber cement remover if particularly greasy. Some areas may require mild scraping with a toothpick to remove waxy manufacturing residue, especially the interior (an ultrasonic cleaner and toothbrush works great for this).
Part Number HOR03a.
