New to me, very old Cookshack questions.

Well, I am a long time lurker with my 14 year old smokette size cookshack. I finally found a deal on a larger unit, and had to join to ask a question.

I stumbled across an old cookshack with this on it's tag model: 15-s/d 614. It has an on/off switch and a knob with no temperature markings, only high-med-low. It is in as good of shape as my small unit and I could not pass on the price ($350). It came with all the original manuals, extra heating element and unused sausage hooks. I had been looking for a larger capacity unit without breaking the bank for the once a year the extra capacity is needed.

I will of course be playing with it after a cleaning, but I was wondering if anyone out there knows rough settings for specific temps?

This thing seems even more simple than my smaller unit with the thermostat knob. It heated up before I bought it and per customer service cookshack has everything except the power switch which is at Granger.

The final question is there any way to convert or add a simple plug and play thermostat switch to this one? Every once and a while the wife will put the food in and loves " turn on to X degrees" and be done.

Thanks for all the help and advice I have mooched as a lurker and hopefully I can contribute something that helps another owner.

I look like the happy nerd in the photo, but had just unloaded the beast. I know a better photo of the contorls might help, but this is all I have right now.
