Need info on Argentine .45 ACP ammo

I would like to get info on some Argie .45 ACP ammo I picked up.

Headstamp is:

11.25x23
FLB 78

Is this corrosive ammo?

Thanks in advance

non corrosive and worked fine in my Thompsons , Grease Guns , 1911s and 1917s back 20 years ago .
Depends on how it's been stored the last 2-3 decades .

Mine came loose in bags but is clean otherwise.
Do you remember what the headstamp looked like?

I was curious about how they came up with the Metric markings. I found this:

The two different metric calibers 11.43 and 11.25 mm for this cartridge correspond to the groove diameter (.450") and the land diameter (bore .442", actually 11.23 mm) of the barrel.

ETA: COMUN = COMMON

You could always pull a bullet and look at the primer holes.
Here's what I found on a quick search..

I had to use google to translate this 1st link. In it some locals in South America say they are 'Berdan' Primers.
