U.S Armourers Tools - ID appreciated

[BOUGAINVILLE]

Here is a grouping of US armourer tools. Does anyone know which weapons that each one is specific to.

I know that (2) Combination Brush Tool is for the M1918 Browning Automatic Rifle.

The Combination Wrench (4) looks very similar to that which is specific for the M1918 BAR but slightly different.

Any help would be greatly appreciated.

Cheers,
BOUGAINVILLE

#1 is a combo tool for the M1919 30 Cal machine gun, and No. 5 is the split casing extractor for same.

As mentioned above:
#1 and #5 is for the 1919 Browning.
#3 is a gas piston wrench for an M1 Carbine.
#2 as you mention is for the M1918 Bar
#4 looks to me like an early M1918 Bar Combo tool....
