Koslow Engineering 1931 Vintage Men’s T-Shirt

Koslow Engineering 1931 Vintage Men’s T-Shirt

$26.95

After some initial success with the Super X model on the dirt tracks during the 1926/27 seasons, Chicago-based Excelsior Motor Mfg. owner, Ignaz Schwinn, instructed chief engineer Arthur Constantine to develop a competitive bike that could capture the National Hillclimb Championship. Constantine went to work, relying on the company’s engine builder and tuner, Andy Koslow, to finish work his magic on the engine. Koslow produced a 45 cubic inch hillclimber utilizing a bottom end based on their “Super X” road model, and a specially cast, top-end with an OHV top-end with Hemi combustion chambers and detachable, bolt-on heads. These machines were set-up to burn alcohol through special aluminum racing carburetors and from the first test run, both men knew they had a winner on their hands. The new engine gave Excelsior the National Hillclimb Championship title in 1929 and 1930. When Ignaz Schwinn unexpectedly closed the doors at Excelsior in 1931, Koslow convinced Schwinn to allow him to retain the blueprints and molds to his engines and promptly opened Koslow Engineering that same year. Koslow would go on to build limited examples of his meticulously handcrafted OHV engines, but really made a business out of designing and building performance parts for other manufacturers, including adapting his now-legendary OHV heads to their powerplants. This design is based on the company logo which was proudly emblazoned on every Koslow made part.

Sizing


Not sure what size is your best fit? We recommend taking one of your current t-shirts, laying it flat and measuring it. The measurements in the chart below are taken with the shirt laying on a flat surface. To get the length, measure from the high shoulder point down to the bottom of the shirt. To get the width, measure approximately 1-inch below the armhole, across the chest, from seam to seam. While our tees are all made using premium, pre-shrunk, ring-spun cotton, there can be some shrinkage depending on your personal wash and dry cycles. With that said, if you’re on the fence, we always suggest going up a size.
