These are the Hasegawa kit. The Bubbletop being a Brazilian machine with aftermarket decals, the Razorback one of the 325th Checkertail Clan using kit decals. For their age, the kits are decent, although lacking in cockpit detail. The Tamiya kit is superior, but the Hasegawa can often be found and swap meets for 5 bucks, in fact that's what dad paid for it about 15 years ago when he bought it for me. It was a 2 in 1 special edition.
