Not likely, but I will add you to the waiting list (the list is longer than most new steel Daytona waiting lists).
Not officially, no. The 6542 was shipped with either the 6636 or 7206, each with 80 ends, which is what I have fitted to my black dialed '42
However, as was the case back then, Rolex dealers had alot more latitude & control over which Rolexes they sold & how they sold them. It was common practice for dealers to offer the customer his/her choice of bracelet/strap & I have a couple of pics in my archives of early, 1-owner '42s sold at auction with (big crown) folded link, jubilees. While I love the folded link Oysters, the jubilee is alot more comfortable &, with the more formal whte dial, I think the jubilee compliments it better than the more workmanlike Oyster.
I generally pair my Aryan 'Master with a '58 folded link 6251H with 55 ends, which would be chronologically correct.
