I have had this old kit since the 70's and its been in storage fro about 20 years. Unfortunately I lost the burout instructions which consisted of where to set the numbered control knob and for how long. It has no pyrometer. At first glance this system looks like a toy with a hand operated vacuum for casting but it actually produced many good castings in it's day. I think the company has been out of business for some time.. I would gladly pay for a photo copied instruction sheet.
I got the name wrong it is Jewelcast. It was made be Classic industries.
