$53.00 for a Motobike frame?

[SKPC]

What is throwing me off is the statement by Scootertrash that this ad was from 1936. I wonder though if seats like those and 28" "armored" wood wheels were the norm in 36. 26" wheel option on smaller frame? No dates on the ad pages, but seems earlier than 36. The 2nd lower end bike seems to be the one though...

Snyder for 34 would be "D" I think. the thing that should identify that frame is the way the drop in the top bar is a soft curve which is then carried into the top portion of the seat stays---not a snyder feature of 34-35 as far as I know. This frame seems to be a few years later--starting to become the fully curved frame of mid-late 30s--on. It's all about those seat stays as far as identification. 36 Huffman??
