Hi, Micheal -
That logo on #483 is based on the Rio Grande Southern, not the D&RGW. It's really not appropriate for a K-36, but VERY appropriate for a K-27 - several of which were leased, and at least two purchased, from the D&RGW by the RGS. IIRC, #463 was repainted as the 'before-the-wreck' RGS #455 a few years ago, and looked terrific. I wish I had been there ...
#461 also had the RGS "sunrise"(?) logo on her tender for a couple of years, just before the end. But she had 'inboard' piston valves, and an extra link in her valve gear, so repainting #463 as #461 won't work - too many mechanical differences, some of which are VERY obvious.
Happy New Year - and apologies for semi-hijacking your other thread!
