There is a 6-cylinder Buick engine, cowl, transmission, and chassis (no wheels) currently on the rarely watched vintage parts car section of ebay, item #360078390715, for a few hundred dollars, no bids yet. It's part of the estate of an old car collector I knew who died earlier this year; been sitting outdoors, but would be a wonderful parts source for someone who is restoring one of these. Located in Derby, Kansas which is a few miles S.E. of Wichita.
Somebody needs this for parts before it is crushed. Most of the engine is there and all of the transmission. Might be as new as 1923, but no older than 1920(?) because it has the rocker arm cover.
