Note: Model and serial numbers may (and usually do) contain both letters and numbers. It is important that letters be entered as letters and of course numbers as numbers. For example the letter 'S' (if present) should not be confused with the number '5' or vise versa. The number 2 and letter 'Z' might also be mistaken for each other. I have a Westinghouse oscillator in the pile with a brass guard and composite replacement blade. The Style# is 164848 with a P or B suffix on the end. Is it a 4 or 6 pole motor? How is this determined with Westy style numbers? Is there some kind of code in those numbers that designate a 4 or 6 pole motor? Deciphering can get a little tricky. In an appliance with the serial number AB920, the 9 could mean 1999 or 2009. You'll have to use your judgement as to whether the appliance looks 15 years old or 5 years old. That number is the Westinghouse's motor style number. The serial number of the actual machine can be a number of places. One would be on the bed of the machine under the motor. One is on the bed of the machine under the front slide plate. One would be on one of the slide plates (which often are lost and/or replaced without the serial number). Sestroryetsk used 'No.' Above the serial number, which means 'number' just as the 'N'. Each year started over at serial number 1. 19: New England Westinghouse used 'No.' Above the serial number, which means 'number' just as the 'N'. Production started at serial number 1 and ran straight through to the end of the contract. (Without Serial Numbers) USA Mfg’d The following transformer welders do not have serial numbers. The date of the manufacture for these units may be determined from the last three digits of the code number stamped on the nameplate. Units Involved:AC-225S, AC/DC-225/125, AC-275, AC-225 GLM, AC-225 SEARS Code Number Example: 9422-001 Code Year Month.
