Ray,
The second team arrived in-country in June, but weren't declared operational until August. The document I got the TOW history from is the official VHPA history written by Mike Sloniker. I'll be seeing Mike in November and I'll talk to him about it a bit then. The FM antenna issue wasn't necessarily that they were removed in the states, just that they were removed before it got to Vietnam.
Judging from the photos we do have, I would say that they both arrived in country with the Strela kits on them. I'm certain that the kill marks were painted on the birds when they were with the first team. We have pics from the end of May that confirm it (group shot with chalkboard kills and both helicopters) and other photos from that period (with fewer kill marks) where the toilet bowl is clearly visible.
I'll tell ya bud, you turned my whole project on its ear last night with the posting of that pic of 62-12553. I just don't see how the bird in the museum could be anything BUT that helicopter! Would the Army have let go one of its two TOW birds? It makes sense that that bird is in the museum and the fact that it still has the TOW system fitted to it would seem to be proof enough!
Ugh... gonna be a long day.

EDIT: I just looked over the TOW Article by Hughie McInnish. We've got pics of him in Vietnam in May 72 and he was the "team leader" with the 1st Airborne Team. Glad to see more info from him. I'm going to start trying to contact former team members so we can get to the bottom of this!
