Fender skirt identification

[ironandsteele]

I am posting this in hopes that someone here is willing to help me with definitive answers to a few questions I have about these skirts I just acquired. I am usually pretty good at sleuthing around on the internet to get answers when I need them, but I have found conflicting information about this style of skirt all over the place, including here. I'm hoping someone with firsthand knowledge can tell me:

-What years they fit
-When they were first available
-How much they might be worth

For context, I bought out a collection of parts from the estate of an early Ford guy that was local to me. Most of it I am keeping, but I don't think I have a need for these and will likely re-home them.

I see these skirts advertised periodically with the claims of "1935-1936" and "1937-1939" and every combination in between. I had always thought that 1935 and 1936 did not interchange when it came to skirts, though I have only ever really been paying attention to that within the context of bubble skirts, not necessarily these flush-mount style.

I've seen them advertised as "original" (as in, stock, 1935, 1936 "Ford" pieces) and I've also been told that Ford did not sanction or offer skirts at all during this time period...

I also see them listed (past and present) in various places for prices all over the place. As low as $800 and sometimes anywhere between $1500 and $3000. I don't know what they actually command in the real world though.

These were labelled as "35/36" when I pulled them out. I did also hold them up to my '36 Phaeton and they fit the wheel well opening perfectly. Does this mean they would also fit 1935?

I hope this makes sense and that someone can shed some light on them for me once and for all.

Thank you in advance!
