Vincenzo,
I hate to disagree with Gino, but most Hal-3 birds were Army UH-1B's (some refs say a few C's and M's were used, but I can't confirm this with photos). A few were UH-1L's, and the Sealords used a few HH-1K's. NO HAL units used UH-1E's (to my knowledge). Those were exclusively Marine birds. The really unique thing about HAL-3 was the way they used their M60A's (although some did use Sagami mounts). Some interprising seaman came up with the idea of using the pistol grip from another M60 mounted at a right angle to the trigger on the forearm of the gun. Thus most HAL-3 M60's were true Free Guns with no bungee or Sagami mounting system. Here are a few pics to show what I mean:

[img]http://[here you can see the band that held the extra pistol grip in place.
[img]http://[Just to show that this isn't some one off mod, here are three gunners with the same modification. In fact, I have photos from all the HAL-3 Detachments showing this system.

[img]http://[Here's a bird taht used BOTH the modified 60A (note buttsock has been replaced with a truncated version similar to M60C) and the Sagami mounting system.
[img]http://[This bird might account for the idea that HAL-3 had UH-1C's, but it is a Bravo model (see nose mounted pitot and symmetrical narrow chord stabs) with a C model tail boom replacement.
[img]http://[Sealords UH-1L (last flight in country). Note the rof mounted rescue hoist which was indicative of the Navy's UH-1L and HH-1K.
50 Cals and Miniguns were used a lot by all the Seawolf deatchments. These were mounted on Sagami swinging mounts for the most part. Check this page halfway down for a bunch of pics of the miniguns and 50 cals used by the Seawolves:

Do you have a photo of the bird you are going to model?
Hope that helps.
