Dating for Excelsior , 1936 ?

[Vicious Cycle]

I can't get the pre-war serial page to open so.. I have # S75988 Excelsior badged Schwinn, No year on crank, 6" head tube = tall frame ?

I think it dates to 1936 but would like to know.

thanks

I believe 502 is part number for 6.5" crank

Here is one list. Looks like 1938

Would a '38 have the straight down-tube ?

 

[SJ_BIKER]

Yes
BC, model C and even some motorbike models for 1938

Thank you for that. I was told '37-'38 a long time ago but serial # charts are all over the board.

Looks like a Hawthorne chain ring on there. Looks like something happened and both crank and ring were replaced.

That is what I was thinking, I haven't seen a Schwinn crank with these markings.
In the catalog pages above, it mentions but doesn't show one with the knee action fork, Is a straight downtube with knee action a common combo?
I can't say I've seen many.
