These came on a Clevenger EUB I found in a pawn shop.
I haven't owned an upright in a while and they seem kind of stiff compared to what I remember the Spiro Weichs feeling like that I had on my last upright.
I saw the thread for the lower tension strings and may try the Spiro solo gauge tuned normally as so many suggested.
Any help on the current strings is appreciated.
(Yup! Purple on the top, Red on the bottom)
Those are just flash artifacts on the body. It's actually in excellent shape.
