45-70 , 45-60 and 40-60?

I just acquired these three ammunition.
None of them have a headstamp.
I would like to have information on the manufacturer of each of them if possible.
Thank you in advance.

I don’t know who made these cartridges, but the top specimen is a 40-60 Winchester, the round in the middle being the 45-60 Winchester I think. With the 40-60 it is necessary to specify ‘Winchester’ as there was also a noninterchangeable 40-60 Marlin. Jack

The .45-70 looks to be made by E. Remington & Sons, but no idea about the others.

The far right cartridge’s primer show signs of Farrington process which points towards U.S.C.CO.

Thank you for this information.
