Can anyone ID these strings?

These were on an Upton "Hawkes" I recently got. I know pretty much zip about upright strings - I played quite a bit years ago but strings were pretty much "whatever is on it" or "sell me some light gage". These seemed pretty stiff to me, but I can only compare them to some weedwackers I bought (obviously not really a comparison!).

If I can find out what they are I may be able to look up the actual tension. As it stands I'm just guessing.

Thanks!
