I decided to photograph the MT500 and holster I just got from all angles since there weren’t a whole lot of reference pics of it available. I don’t know if the holster itself is 100% accurate, but it’s real close. I do know in the movie you can’t see the word Morotorola on the front of it, and the right side may or may not have that angled bit.

The gray front and rear panels are 7 9/16" tall, 2 9/16" wide (across the bottom) with a bevel approximately 1/4" in radius on the corners, 1 19/32" deep at the bottom, and 1 27/32" deep at the top.
The top of the talkie is flush with the top of the leather holster when seated in it, but the holster is 7 3/4" tall. When seated in the holster, there is a 1/4" gap between the back of the talkie and the back of the hoster, caused by the spacer in the bottom which creates a tight fit.
The solution is to either cut your antenna down and replace the cap - it’s just a coil of wire inside - or buy a quarter wave UHF antenna tuned for about 600Mhz. Anennae are not expensive items.
