Agree with
@QuelleFromage . I don’t know why your local boutique won’t accept your bag for evaluation, and/or wouldn’t give you an explanation, assuming that you brought it in personally. ( I always assumed one had to bring in the bag to evaluate whether this can be repaired, especially in a tricky case, but that is simply bc it is what I have always done ).
An exotic repair can easily cost more than the resale price of the bag, especially if you got a good deal. If the skin is damaged, and a panel or entire part has to be replaced, it may not be possible or worth it. A specialist may need to evaluate your bag, and there may not be one on site.
ETA: I don’t know what repairs Madison would do versus what it sends to Paris; I don’t know if you need CITES to transport or even to have it sent back to CA; or if that is possible given CA’s restrictions on exotic leather (including lizard as of 2022) . I am a solid Madison client (both retail and repair), and I also have to say that it can take a very LONG time to get a quote. And, even longer to get a repair. In this scenario, and others related to repair, your SA can also help/advise. Both SAs and repair are usually excited to see older bags.
