Nope, he was Mr. Controls.

Mr Controls
Hi John, thanks for the documentation on our little friend from Robertshaw.
I would have sworn that his name was Robby Rheostat, I will have to do some digging to see if his name was changed at some time, but I could certainly be mistaken, [ it has actually happened before ] LOL

I remember that building and the neon sign of Mr Controls near the New Stanton turnpike exit from many turnpike trips I remember from the 70's...the building is now occupied by Westinghouse[this post was last edited: 10/9/2018-19:51]
Robbie Rheostat would have been a great name. My father, grandfather, and an uncle worked for Robertshaw or a predecessor and we had Mr. Controls-branded promotional stuff all over the house. There were even some playing cards at one point.
Oven Calibration
Thanks for all the feedback guys! I've been using this range for the past few weeks to run it through its paces and it bakes and cooks like a dream!
Have a question on the operation of the oven thermostat.
The oven appears to run a bit hot - I think. It does have a preheat cycle but I get the same result whether it is used or not so I don't think that has anything to do with it.
During preheat, the bake element will cycle off almost right at the temperature setting however the residual heat from the element as it shuts down pushes the heat about 10-15 degrees warmer.
Similarly, the oven cycles back on right about at the temperature setting. As such it seems to maintain a temperature between 10-20 degrees higher.
Should the thermostat be functioning in this way? For instance, if you set the oven to 350 should the element cycle off right at 350 or should it be somewhere between 335-340? Similarly, should it cycle back on right at 350 or should it be at a point below the set temperature?
I understand it would be impossible for the thermostat to maintain the temperature at the exact setting but what is considered an acceptable range? Using the 350 example would it be something like 340-360 or less precise than that? Or is 350 really just the cycle off/cycle on temperature?
There is an adjustment underneath the knob on the switch but it appears to be 3/4 of the way fully adjusted so I haven't touched it yet. I did check the sensor and made sure it wasn't touching the wall of the oven.
In terms of my test equipment, I'm using one of those $5 oven thermometers. I'm assuming there is also a margin of error in these but I'm not sure how much.

There is always going to be some overshoot in the temperature, I think your numbers are quite good. My current use stove has 15-20 degree overshoot. Did you run this test empty? Maybe with a food load the effective average temperature at the food perimeter will be closer to set temp. Also did you test say 30 minutes later when all parts of oven should have a stable heat loss? If so you might try to adjust thermostat to turn on at say 340 so the 10 degree + or - is equal around your set temp. Enjoy your quality built vintage Moffat.
Oven Temperature
I would leave the calibration alone, Thermador always instructed us to set their ovens exactly the way yours is running. They said to never let the temperature go below the set point, that way the customer had an oven that cooked on the FAST side of what recipes call for the cooking times.
Likewise I am sure that you can get used to your great Moffat vintage range cooking everything on the faster side.

Thank you gentleman - that makes perfect sense. Yes I've monitored it both empty and with food and observe similar results. Appears the oven is very well insulated as it maintains some pretty good heat for sometime after it is shut down. I've used it for loaves of bread, buns, pie, a cake and a roast and it baked wonderfully so I'm going to leave well enough alone. Thanks again guys!
