Hey all,
Well, Chris and I did a little bit of legwork yesterday. Having been in contact with 554's crew chief, we confirmed that 62-12553 and 62-12554 are the correct tail numbers for the TOW birds.
Ray was right, and I owe him a big thanks for continuing to push me with the research!
For some reason, 60-3553 and 60-3554 are at the museum at Rucker. 553 has the XM-26 system on it. Because of that (and the mods made to it to put the system on it), along with documentation from the TOW team that just refers to 553 and 554 (no full tail numbers) it seemed that 60-3553 was the correct number.
That being said, with a little research, we determined that 62-12554 is about fifteen miles down the road from my house! She's been sitting in Air Force colors, with a bogus UH-1F engine cowling on her, but she's the real deal. She's got a bogus tail number on her too, but I was able to get a shot of the panel and it confirms that it is 554.
So, right now, I've pulled the model out again and will be doing some more work on it today.
In the meantime, here's 554 as she currently sits:
