I've got all 3 20th Primes misb with trailers, but I only want to display one out of the box with trailer. The first Prime is the American version with black and blue gun, long stacks, and MP-01 Just Toys trailer. The second one is the DVD Prime. The last one is MP-04 with grey gun, that's the color of gun on box. What are the differences between the Mp-04 and Just Toys trailer? Which gun was more rare in the 2003/2004 20th American version? Does the 2004 version have Diecast like Mp-04? Also does MP-04 have battle damage?
