So about the LeKP M41 90mm GF in-game model

Lert: Eh, that's just a skin / texture. The MG was actually modeled. For the regular Bulldog, but still.   They could've copy-pasted the Kanonenjagdpanzer's MG3 onto the LeKP model if they wanted to, so I'm wanting to know why they kept the ,50 cal HMG.   Was it an oversight? Was it a conscious choice? Do they have information suggesting the germans actually used the M2 instead of MG3? Or did they just not care and wanted a quick-and-diry retexture to put into the game? The model's changes to the gun mantlet and gun suggest they actually put some effort into this premie, so why not simply swap the Ma Deuce for the MG3 from Kanonenjagdpanzer?
