I've noticed I'm not the only one searching for some of these repaints that have been around since 2010 - some of them, anyway.
There's a man named Nathan P. Phillips who has made a number of very good repaints of this aircraft. Quite a few are listed on the CS free liveries site for the B-52, but going to the "download" button shows the site to download them from to no longer be active. Persistence pays, however, and two of these repaints, listed toward the end of Mr. Phillips' offerings, did in fact download after I went to the "download" button on the CS site.
I've noted these downloads are both identified using a 10-digit number. That brings to mind the avsim.ru site, and I'm wondering if they are still carrying Mr. Phillips' repaints over there. To my memory they are the only site I've ever downloaded anything from that generally uses a letter-number convention to identify a download.
I've tried straining his name through the AVSIM and FS site libraries to no avail.
