I currently have an updated version integrated with the other WW2 weapons in a single pack. The weapons can be found on my server(Server runs two gametypes: KFMod 2.51 and Regular KF). The Regular KF vote option has the custom shop mutator with the WW2 weapons.
This is the link to my server if you like to try it out:
205.234.153.2:7707
And this has some of the server files which includes the WW2 weapons(Incase you would like to play them in SP with custom shop.)

If you use the custom shop you will need to add this to your shop's ini file:
WeaponForSale=KF1945weap.TT33Pickup
WeaponForSale=KF1945weap.PPDpickup
WeaponForSale=KF1945weap.m44pickup
WeaponForSale=KF1945weap.g43pickup
WeaponForSale=KF1945weap.g43scopepickup
WeaponForSale=KF1945weap.mp40pickup
WeaponForSale=KF1945weap.stg44pickup
Also files have been supplied to a couple of servers most notably KF Legion.
