I have a slightly earlier version of that bass! I think they're a nice instrument, and I've been watching complete ones in good condition sell on Ebay for $300+. Mine has the earlier headstock, yours has the later headstock to qualify it as a "Coily" model.
I even have a pair of pickups for it! They're a different style than those - more the style found in the Epi models with a white insert around the pole pieces.
I also have a tailpiece and bridge which are 100% correct for it - I was going to sell them with my walnut Lyle, but I might be persuaded otherwise....
The tailpieces and bridges WERE the same on Lyle, Epiphone and Univox. The bridge on mine still has the flip-mute and cover over the saddles, but those were very often removed. The only difference in tailpieces is whether it has a rosewood insert or not - the one on my Univox does not, the spare I picked up does.
Here's mine (and the lousy string-winding in the last photo wasn't my work - it has now been corrected):
