I just heard from Lewis at superdenim that The Real McCoy's has just struck a deal with Levi's; they will be making the 1947 501 for the Levi's Vintage Clothing collection. There has been complaints about the existing '47 not being an accurate reproduction because it's so slim, but this should be the last say on the issue as the owner of The Real McCoy's has thousands, not kidding, of vintage Levi's to base the jean on.
I'm not sure when the RMCxLVC '47 will be available nor where it will be available. I do hope, but not expect, that this model will be sold in every country where LVC is sold.
The Real McCoy's has already made a few models for Lee, but I'm not sure if or how they are better than the Edwin-made ones.
