Those are SR350 series medium duty Victor regulators. The CA1350 is a medium duty cutting attachment that fits the 100 series handles. I have a 100FC handle with the built-in flash arrestor/check valves. Not sure of the e44f4-1.
About 2 years ago, the Super-Range II set with a rosebud was $275. The current Performer set with the newer EDGE regulators is available on the web for $220.- $230. delivered. A new 80 CF tank is about $190. Bargain a little. (I saw a nice Journeyman torch with handle locally for $40.)
