Odd in the fact it doesnt have the classic shepherds crook bell tube, just a straight bend off the valve block.
The reason for ranges overlapping the years is that serial numbers were assigned when instruments were ordered by dealers and before manufacturing. Serial Number: Year Manufactured : 3070: 1905: 9000: 1908: 9950: 1912: 10,800: 1916.
Some solder on the joint between 1st valve& shepherds crook, suggests there may have been a repair.
