Well @MajorMcDonalds hope you guys take notice of this so lets start the topic
First why?
Simple the name is misleading and is wrong so you might ask what the real name well it is complicated let me explain a bit about Mauser pre-war machine carbine and why it was made
So explanation
During 1930 WaA(Waffenamt) asked for investigation on small arms future on July 24th a report came back which essentially explained that 50/60% of major fights would be at around less than 400 meters and that 30/40% would be around 400 to 800 meters and less than 10 % would be at more than 800 meters
Though the report doesn’t mention which caliber these automatic carbines should fire , IWG report back in 1924 mentions that 8mm Mauser is too powerful to be able to be controlled when shoulder firing
What this leads us to?
Well it leads us a fey years future where German industries have developed few intermediate cartilages and WaA has a program for automatic carbine going on with Mauser , walther and Volmer competing in it (More like Vollmer peresnted weapon to WaA and they decided to test it and other companies find out about it and they present their weapons,too)
what now ?
We know about these prewar weapon and that DWM short ammo is pre-war ammo what does that say ?
Only logical conclusion would be that MKB 42(M) with DWM ammo is prewar prototype
Any person with logical thinking would connect dots, Mauser failure with G35 rifle (Already suggested in one of my axis weapon suggestion) and DWM failure , and since they both helped each other develop the round that rifle from Mauser would be chambered for this round and presented for WaPrw2 pre-war for testing
And?
And we reach the name phase initially I asked for changing the name of the gun for MKB 42(M) early or
MKB 42(M)(DWM) why? Well because Mauser as soon as it noticed that during 1941/1942
another machine carbine trial was going on decided to enter the trial but since 1942 trials were all done with Polte round(8mm Kurz) it changed the ammunition and entered that competition
And later variant of MKB 42(M) had some minor diffireneces
And some minor changes like Bolt and nozzle cone(A gas port was drilled in nuzzle cone as per suggestion of Branch 44)(Which our in game model doesn’t have making the gun in game pre war model)
And odd find
During my research I also came across the name Mauser MKb 39 (Robert first mentioned it in Forum) which IMFDB mentions which might be right but I couldn’t more information
Conclusion
As per evidence above I suggest that name of the MKB 42(M) be changed to MKB 42(M) early or MKB 42(M)(DWM) or Mauser MKB 39
Thank you for reading the topic
