Hello,

I recently picked up an ITR master clock that has its model number/serial number tag missing. Would someone give me a model number/letter and an approximate date of manufacture based on the information below. Ask questions if more detail is needed.

The clock came out of Gamewell in Toronto, a company that produced fire alarm boxes. The clock is running but needs a service. Not my usual, but I will leave the case and brass grungy. Something inside me will make me touch up the case (paint specks, scuffs) Since the cables are the long ones and frayed a bit, I am hoping to shorten the cables to get rid of the frayed sections and also stop the weights and pendulum from contacting each other as the weights run down with the electrical feed interrupted.

The numbers with the description refer to the photos attached.

1. quarter cut, white oak case, Corbin locks, there may have been more to the bottom

2. dial with scripted numerals, larger version of subseconds dial

3. brass beat scale, note two holes where longer style id tag used to be

4. the "360" that is stamped into the case (left, bottom, inside)

5. mechanicals with no peripherals (were removed by previous owner, a Simplex employee)

6. movement with no "ITR" stamp, later style anchor adjustment

7. motor with two oilers and rubber mounts, AC motor NP 21163, model no. 23225 CF, type SDA, freq 305, HP 1/70, V 110, cycles 60, phase 1, rpm 3000

8. black painted pulley (with stress fractures!!), older style contact limit switch, newer style cable drum assembly with the 1/4" shaft (no loose bearings??, I hope!)

There is also a 35-7 and a 16-7 in my basement. This looks a lot like the 16-7 but with the brass beat scale, brass covered weights, brass covered lenticular style bob, and other early features.

Jim

Hi Jim, this clock movement sure looks like it was well cared for, clean and the slotted screw heads look pretty good. The adjustment for up and down on the pallets, mine is pretty much all the way down.

There is a guy name Detrich/Dietrich who has several shorts on you tube one of them has many clues, such as type pulley etc on dating the clock you are inquiring about. He has done well researched good quality videos which I believe will help you.

Hello Scott. Okay, Model 16.

Hello Paradise. I've seen the Dave Dietrich YouTube videos and explored his website. I should probably send him an email with my list of characteristics and have him venture an opinion. Most of the characteristics that I choose to list were from his website (two motor oilers versis one, for example).
