Can anyone provide some guidance on the different fork struts used on prewar Schwinn models? (non-springer forks) There appear to be two main shapes for the struts; the older one has a bent angle right where the strut goes through the loop on the fork arm. The newer struts have a gentle curve that extends downward from the strut mount and then is straight by the time it goes through the fork arm loop. Is the difference in prewar fork struts by model, such as motobike vs autocycle, or by year? What models or what years? When did they make the change? Thanks My apologies if these are your pics, borrowed them from here on the Cabe to illustrate the difference in struts.
