First timer here with a question for the community: I have a pair of LVC 501/1978s rigid/unwashed that I bought online steeply discounted as dead stock earlier this year from Aero Leathers in Scotland. I did this because LVC discontinued the '78s. (I stocked up on my size, 32 x 34, when the '78s were discontinued-- I like the fit best for me.) Comparing them to other unwashed, unworn LVC '78s I have, there are some differences between them: The denim on the ones from Aero is distinctly different; it's slightly bluer and not hairy at all like on the other '78s. There is a larger rise (about an inch more), thigh is slightly larger and the leg openings are about 1/2" larger than the hairy denim pairs unwashed. They also have an extra button in the fly, 4 plus the top button, as opposed to 3. The interior white label says Made in USA but it does not mention Netherlands as a Levis business address. Instead it mentions a Levis Brussels address. Also there is no hang-tie label (with size info, big LVC red logotype, etc.) nor is there a repro vintage envelope in the back pocket. The style number on the pair from Aero is 78501-0001. The other '78s I have (from LVC site, shops and elsewhere) with hairy denim, repro vintage envelope and hang-tie label have the style number 78501-0002.
Does anyone have any knowledge to impart regarding whether (or not) the pair from Aero are Cone denim, bootleg or not, actually USA-made, etc.? My initial thought is that LVC retooled the '78s at some point and they are a relic from the period before they did. I can upload photos if needed. Thanks.
