Maybe some didn't know any better cause they didn't see the difference or didn't know the 47 was largely superseded by the AKM since way way back in the 60's hence it'll be much accurate, realism wise,to pimp a AKM than a 47.
Well,what's worse is even a manufacturer like G&P doesn't know better,remember around october last year they came out with a series of conversion kit that has the 47 metal body coupled with Galil-type folding metal skeleton stock, a AKM type fixed stock and M4-type stock? A TOTAL WASTED OPPORTUNITY!!
I hope G&P knows,i'll say again---
