I'm not certain either way and I'd believe that scenario. I'm perfectly happy for it to be civilian, as it will be used either way, and I picked them up cheaply as part of a job lot.

I think maybe the 1162 stamp accompanied by a date in the same place on both of them undermines that interpretation somewhat, as I've never seen anything similar on a civilian version. If it's re-use of previously stamped military material I wouldn't expect it to be in the same place on both of them, or there at all.
