Orange serial number query O2 EVO

[2manyoranges]

I thought I understood Orange serial numbers but I have this O2 EVO frame hanging around which has two numbers on it, which don’t seem ti follow the same rule as early steel frames (first digit year, second two month).

Anyone with any ideas?

First number
M191201293

Second
A410-8

Grateful for any help
Thanks
Tim

I haven't got anything on my list with a similar range serial number. But I only have one other O2 Evo listed and that starts with an 'IT' frame number. Can anyone else with an O2 put up their number?
The additional numbers shown may be useful at some point. I've got similar recorded on these two as yet unidentified frames:
