Help With Robocop's Auto 9 Prop Replica
So, I purchased a Robocop Auto 9 prop replica, and I'm not familiar with the terminology or names of the parts but, something seems a little off, and I'm not sure if it's supposed to look like this on one side.
As you can see I've highlighted the areas with a white circle, you can see a ridge line which separates the top and bottom part of the barrel? but in the picture where the trigger is to the right of the picture you can clearly see this ridge line is gone, it's smooshed, the area seems smudged, is this normal? I mean for this prop, is Robocop's like this in the movie?
I've looked all over the Internet and it's definitely not like other pieces I've found.
Although on the prop makers website where I purchased this from, I've gone back and has another look and it's the same in the pictures as it is in my hand , I can see this area in the website pictures but didn't notice it at the time of purchasing it.
Your help would be much appreciated,
