Don't recognize that brand here is one that is similar in design http://www.johnsongas.com/industrial/frn-atmos.asp
Does it have a blower? atmospheric furnaces are limited to melting aluminum or other soft metals. With out seeing more of the piping it would be hard to tell if it had controls or could be added. A pid controller, thermocouple, and gas solenoid can control a flame, but it needs a relighting system like a pilot or spark ignition.
1st thought it was a tempering or annealing furnace. But since it came from a jewelry manufacturer, I think the process is cloisonne where glass powder is fused to metal, like old car emblems. It's not something you connect a bbq tank and just make work, will need more research like what size orifice it has and if it is propane or nat gas low or high pressure? It can be made to run like a new one! 100$ isn't bad but 50 sounds better, but I'm cheap! Also the brick will contain asbestos so be careful with them. If it needs new bricks I will recommend Mizzou mix from APGreen/ Harbison and make a sheet metal form to cast them in. A tough durable bricks once cured! It is a well made furnace!!! I'd probably would buy it if it was close and I had help loading and unloading.
