Dials shown are for the Ball and Co ORRS Watches thru 170K
I have not shown any dials relating to Brotherhood or P&L movements that are also found in these runs.
I would expect them to follow the same pattern but have noted two BLF's early in the 42k run that might be exceptions. They have wavy 3 earlier type dials. Later BLF's in the same run have the expected flat 3 numerals.
The 90K and 170K runs also have commercial std movements and those dials are not pictured either.
Ditto the RRWCo dials found in the 90 k run
Somewhere in the 170 run, movements and dials transition to Ball Watch Co.
Note the Fancy A in Cleveland!
Above is a pic of the earliest Ball and Co ORRS dial known to me, It is found in the 13001-13400 Ball Hamilton 999 range. It is possibly also found on the 8701-8800 Ball Hamilton 938 run. I am not sure as there are only 3 reported in that 938 run and I have not seen pics of 8711 which is reported with a patd dial. # 8782 has a replacement Ball Watch co dial and my 8774 has a replaced dial identical to the ones found in the 14k and 28k runs.
Above is a pic of a dial that starts with the 14k Hamilton 999 run. This dial is identical to those found on the 28K 999 run.
Above dial is the flat 3 design that began with the 42K run, It is also seen in the 118K run and on SS Ball & CO ORRS watches in the 170K run .
Above pic courtesy of Fred Hansen Via Ebay. It depicts Ball and Co DS dials found in the 90K run. I believe it to be also found on DS dials in the 170K run.
