Faded name plate

Name plate was faded badly. This is the best I could do. Can someone tell me the age.

Best guess is December 1988

Thanks Erby makes sense to me as well.

Very, very close, but I believe on that one (a 10-digit serial number instead of their standard 9-digit number), the “L” is the manufacturing plant, leaving the 8835 as the year and week.

Was the L preprinted as part of the label plate? That would make it a definitive manufacturing plant letter.

Yes it was preprinted RR sory for the delay. Thank you guys for the help
