My pardner 410 and tracker 2 20 ga barrels didn't. I had the same year Topper 158 in 30-30 as yours that came with a 20 ga Topper Jr barrel. If you watch I've seen other shot gun barrels from that era come up on the classifieds from time to time - but not rifled barrels, smooth bores. I actually sold the 20 ga barrel of mine in the classifieds if I remember right for $65.
