Help Identifying one Barbell and three Curl Bars. Ivanko? Troy? Gaspari?

[Conquer92]

Picked up a ton of bars from a seller for dirt cheap. These are the ones that I do not know what they are.
If you have an idea of what this bar is please let me know so that I can resell them on Craigslist accordingly.

1) Barbell. Odd grip, has three rounded edges and three flat edges. 45lbs 7ft. Brass Bushings.




2) Curl bar. Odd grip, rounded and flat on handle like the barbell. 22lb 4ft.



3) Curl Bar. 30lb 5ft. Does not say Ivanko or Troy anywhere. Bushings are black.

4) Curl bar with rotating handles which are slightly offset like a EZgrip. Gaspari? Split sleeves like York. 4ft 30lb

The ones with the flattened bar stock might be Tri-Bar or something similar. I've also seen similar bars marketed as Tri-Grip. The one with the handles looks like a Gaspari bar

This is a Criterion Bar. It is their lastest version, not the version advertised by Gaspari

I have an EZ-curl bar that matches number 2. It came with some used Ivanko revos I picked up. Grip is weird, I don't really like it. No idea who made it.

IIRC, Ironman magazine would sometimes show the 2nd bar you listed being used in the late 90s/early 2000s. Ironman usually would name the special equipment used in the photo. The gym I used to work at had one of the original Criterion Curl Bars. It sat there collecting dust the whole time I worked there. I offered to buy it. The owner balked. He liked HAVING an assortment of equipment whether it got used or not.
Rich Gaspari was ON TOP OF HIS GAME at this time. He was preparing for the Pro World show that was now christened the Arnold Schwarzenegger Classic. Same people(Arnold & Jim Lorimer) ran the show, they changed the name to capitalize on Arnold's success in 1989. Mike Christian won the last Pro World in 1988. Gaspari included this bar in his photo shoot claiming it gave him a much improved bicep peak for this show. Here's video of Gaspari @ 4:36 using it in preparation for the 1989 ASC. Notice he and his training partner are wearing Criterion tank tops:

This was his best show. I believe he showed up at the Olympia too heavy and placed fourth. He soon tore a pec and didn't place high again.
