Unheadstamped .427, .440 and .450 ID

General Ammunition Discussion
#1

I picked up a heap of new cartridges for the collection over the last couple of weeks including a bunch of unheadstamped items. I have identified most of the them but these few I am not so sure about.
I dont have the greatest reference library so would appreciate any input on ID and possibly features that would ID the manufacturer.

Measurements are (in order from left to right):
1
Projectile dia: .427-.429 (10.86mm)
Neck dia: .430 (10.92mm)
Base dia: .435 (11.10mm)
Rim dia: .502 (12.80mm)
Case length: .845 (21.38mm)

2
Projectile dia: .440 (11.18mm)
Neck dia: .442 (11.28mm)
Base dia: .442 (11.28mm)
Rim dia: .510 (13.00)
Case length: 1.015 (25.80mm)

3
Projectile dia: .450 (11.44mm)
Neck dia: .455 (11.58mm)
Base dia: .460 (11.68mm)
Rim dia: .485 (12.36mm)
Case length: 1.10 (27.96mm)

My identification is:

1 - .44 S&W American (by ???)
2 - .44 Evans Old Model (Phoenix Metallic Cartridge Co. or American Metallic Cartridge Co.)
3 - .44 Colt (WRACo)

In Austrailia you will probably get the greatest mix anywhere in the world of cartridges of this type. They could just as easily have come from Birmingham or Belgium.

Thanks Fede
I had come to the same conclusion for 1 and 3 but number 2 was the one I was really not sure of.
Is that a confident ID?
