Were all Illinois Bunn Special 16s movements marked "Motor Barrell" considered to be 60 hour movements? | |||

The simple answer is no, not all "Motor Barrel" marked Illinois 16-size movements are 60-hour. Fact is there were "Motor Barrel" movements sold by Illinois Watch Company prior to the "Sixty-Hour" mainspring introduction. There was also overlapping in production and additionally certain 60-Hour 16-size movements were not necessarily marked as such so it can get a little confusing. If you provide your movement number that would help in narrowing down exactly what you have. Lindell | |||

Thanks! The movement # is 3654711. It is listed as a 16s Bunn Special 23j. Just wondering if "motor barrell" does indicate it is a 60 movement thanks again!!! | ||||

The database says, no. | ||||

The first 60 Hr BunnSpecial was SN 4,492,501. These were model 14's. The model 13 was 60 hr and came out at SN 4,166,xxx. The model 13 is a 17S and is a Sangamo Special. Tom | ||||

Foster, So now you have three "NO" opinions! To flesh it out a bit further, according to the Illinois Factory Records your movement number 3654711 is a 16-size, Lever-Set, Open-Face, 23-Jewel, Model 11 Bunn Special from 1920 production. It is important to recognize the first 60-Hour Movements were not introduced until 1924 which is obviously 4 years later. The earliest 60-Hour, 23-Jewel Bunn Specials show up in a run which began at the 4492001 movement number. But as stated earlier 60-Hour was phased in and there were many Non-60-Hour Bunn Specials intermixed into that and subsequent runs as well. This is a complicated subject. About beginnings, Tom is correct on the earliest 60-Hour Sangamo Specials (UN-MARKED 60-HOUR) at 4166001 movement number. A lot of collectors and unfortunately many sellers improperly "assume" the three screws on a ratchet wheel or the words "Motor Barrel" mean 60-Hour Mainspring. Motor Barrel marking on a movement means Motor Barrel, the mainspring style is yet another matter. Rather than generalizing we should check the number. Show your seller the real-deal below.

Thank you to all for the info. Having access to such a large # of experts has made collecting so much easier. Although it is not a 60 hour, I think I may buy it anyway. The movement appears to be very clean, it has a really nice montgomery dial and is in a Bunn Special Case. Thanks again! | ||||
