The MACK Model AC Bulldog Chassis
Manufactured by The Mack Brothers Company
Allentown, Pennsylvania
Shipping Soon
In 1916, the Mack Truck Company introduced the AC, an all new truck design that was destined to make history. The Mack AC was granted 18 different patents and was available in three different payload capabilities. The AC featured a chain drive powertrain and a chrome-nickel steel chassis that was very strong and durable. The AC was an immediate success in the United States but it was its popularity in Europe during the great war that earned the AC its now famous nickname the “Bulldog”. British soldiers loved the rugged American truck and started using the nickname as a nod to its toughness and distinctive front end. In 1922 Mack officially adopted the Bulldog as its corporate symbol that is still in use today. With over 40,000 units manufactured, the AC Bulldogs were in use through the 1950’s and 1960’s, well after production ceased in 1938. The MACK AC Bulldog was arguably one of the most important truck designs in American history and certainly holds a place of honor as one of the most iconic trucks ever produced.

The MACK AB Flatbed Truck
Manufactured by The Mack Brothers Company
Allentown, Pennsylvania
In Stock and Ready to Ship
The Mack Model AB was first introduced in 1914 with more than 55,000 units produced. This medium-duty truck’s simple yet classic styling made it a very popular truck and the design remained relatively unchanged until it was discontinued in 1937. They were made in 1.5-ton, 2-ton, and 2.5-ton capacity ratings. Depending upon the gear ratio, the AB had a top speed of 13 to 25 miles per hour. The inspiration for this shortened frame version is based closely upon the CHB Models classic white metal kits produced by Charlie Brommer and myself for many years. The AB Flatbed Truck kit includes an easy to assemble body and bed, the tank behind the front seat, stripwood, details and a selection of blocks and brass chain for you to rig up just about anything.
As with all SierraWest 3D Printed kits, assembly is very straightforward allowing you to focus on painting and weathering. Instructions can be downloaded from the SierraWest website with the provided link. This was such a fun project and I am certain you will find a home for this classic piece of Americana on your layout, diorama, or in your collection. Logs and hose not included.

Ford Model TT Flat Bed Truck Kit
Manufactured by the Ford Motor Company from 1917 to 1928
In Stock and Ready to Ship
The Model T debuted in 1908 and was the earliest effort to make a car that most people could actually afford. It became so popular at one point that a majority of Americans owned one, directly helping rural Americans become more connected with the rest of the country. The Model TT was based upon the Model T but had a longer wheelbase and heavier frame/rear axle making it the perfect light duty truck. The truck debuted in 1917 selling for $600.00. Ford only sold the engine and the chassis leaving it up to the buyer to either custom complete the truck cab and body themselves or pay a coach builder to finish it for them. My kit is based upon a homebuilt model that was recently photographed out there "in the wild”. By the mid 1920’s Ford offered a factory built cab. By 1928, over 1.3 million Ford Model TTs had been sold, wow!
With just 16 pieces, including a single piece chasis and cab, this is a fast and easy kit to assemble and weather. I have always wanted to produce a truck kit with the hood open and motor exposed! Simple and very effective storytelling. Look how prototypically thin the hood has been printed as well as the vents. Folks, those vents are actual vents. The open hood and motor is a single piece as well, such incredible detail. No hassle assembly. Included is a solid body hood in case you don’t want to model the open hood version. This kit includes laser cut window acetate and stripwood to complete the bed. As with all of my 3D Printed parts, damaged pieces will be replaced at no charge. A shipping and small packaging fee will be assessed to cover costs. The details pictured in the bed are not included, available separately. Photographic props are not included. The photographs illustrate an assembled, painted, and weathered model. Assembly, painting, and weathering is required. A link to online instructions is provided with each kit. Prices listed do not include shipping.

The Linn Tractor
Made by the Linn Manufacturing Corporation
Morris, New York
In Stock and Ready to Ship
Linn Manufacturing of Morris, N.Y. began production of its patented Linn Half Track Tractor in 1916. Designed to overcome the problems of hauling large loads over rough terrain, the secret of the Linn's success lay in its unique rear-end crawler-type traction unit. Unlike most rigid crawler designs of the day, the Linn crawler assembly featured a flexible track-roller design. The gear-driven assembly incorporated track rollers able to follow irregular ground surfaces ensuring it maintained positive traction. The Linn was able to pull loads through adverse conditions including mud, snow, and ice.
Available in two body styles, the stakebed and haulbody, each version features different cabs and wheels. An optional accessory package includes an open cab with searchlight, a ski sled attachment, open hood, and an extra set of both wheelsets. Since the parts are interchangeable you can mix and match as desired to create a version of the Linn Tractor that is uniquely your own. As with all SierraWest 3D Printed kits, the Linn Tractors feature incredible details with superior quality prints. Minimal clean-up and ease of assembly means you can spend your modeling time with the fun stuff, weathering and assembly! Laser cut mylar is included for the window glass and stripwood is included for the stake bed. Online instructions provide clear directions for weathering and assembly.
