question about 41AE magazines ?

[wonderdog451]

I have several 41AE magazines in my collection, but one of them is marked 41AE on one side and 45ACP near the bottom.Is that an mistake made when it was manufactured? I am currently using it to hold 10mm cartridges and it feeds those quite well.:smash

not really a mistake...it's just the same mag was used for both calibers, and remarked...but maybe not completely remarked.
I'll have to dig mine out and see what they say.
