So I'm thinking of getting one of dem Patlabor MGs, but Ingram 1 seems nearly impossible to find, and I feel almost dirty buying one of the non-main character ones, but then again, it's been a while since I watched the show, was there any difference between all 3 other than pilot and number stamp?

Also, anyone has any experience with the MGs? do they include all numbers on the decals or just the corresponding one to the kit you buy?
