Epi Strathopoulo Tenor.....keep it?

I found this banjo in my attic, still in the case. It has a floral decal on the back that's pretty much worn away in the center area but the body and all of the hardware is in good shape. Should I keep it and make a five string out of it or leave it as  a tenor and sell it? I already have a Vega Style N  that I can use for a tenor if I need one. If needed I can post some photos.
