I'm going to get a couple of other photos, but does anyone recognize these gut strings? They're on my decesed uncle's 1940's Gibson bass, that I have a thread going on in the basses section. It appears that the E and A have a black winding and the D and G are plain gut, all have tail-end silks. I've ask for a close up of the peg end silks and the windings mid-string. I suppose they could be nylon, but they look like gut to me.
