Jeans w/ 4170 code are definitely made in Cali, but I'm not sure exactly where (Denim Tech maybe?). It's possible that the J. Crew exclusive is exclusive due to their wash and the "85501..." number is the code for this particular model. These appear to be two different codes, one for the factory and one for the model.
I think back in the day, the product code of LVC was 7 digits...the first two representing the model year, the next three the lot number and the last two the wash. It used to be that rigid/raw 1947 501s would have the product code, 4750117.
Not sure I answered your question, but I gave it a shot.

I've heard they are rumored to be made by Caitac Garment in Gardena, CA, but I called them today and they said they don't make anything for Levis or LVC.
Also, if the jeans are 501xx Levis, and have a 4170 stamped on that button along with every other detail a genuine 1947 501xx repro would have (capital E red tab, 2 horse patch, red selvage on coin pocket and outseam, zinc buttons, chainstitched hem, gold colored thread, silver lining on the wash tag, characteristic twist on the outseam), does that necessarily mean they were made by LVC? Is it possible that Levis commissioned someone else to go through with all of this besides LVC??
I ask because I have a pair from J Crew that have 855010001 printed on the wash tag with all of the above details, rather than the typical 47501... printed on LVC repros. And there were no LVC tags on the jeans when they were purchased new from the store.
