wiper motor date code

The date code is the 288th (Oct 15th) day of 69’
 
Hold the Fort !

0438- Isn’t it the 43rd day of 1968. Hence the 3 digits in front of the 8 to make a 4 digit code in all Ie: it could be built up to 3658 for the 365 day of 1968.

Otherwise they wouldn’t need a 4 digit code. They would only ever need a total of 3 digits to represent the week that it was made. Ie 528 would be 52nd week of 1968. There would be no need for the 0 on Roberts motors if it was a week year code
 
As above. 43rd day of 1968.

Yep, I flew by that as well and agreed. 43rd DAY, not week. Good catch..
 
Yes, that's the part number. Isn't a 4-digit number designate the day of the year ? (ex. 0438 = 43rd day of 1968 )
I stand corrected since I only ever had the 2 speed, which only used a month and 2 digit year for a date code.
