I purchased some old Estes motors from a local hobby. These are old stock and they have motor numbers I need converted to todays motor numbers.
They are:
8m3
22m3
22m5
28m6

I found the meaning of these codes.
Please disregard
Enlighten the rest of us - I was completely baffled (not surprizing) by the nomenclature you presented.
These are production date codes. The first set of numbers are the day, the letter is a year code and the last number is the month.
Here are the year codes.
E 1974 M 1982 U 1990 C 1998
F 1975 N 1983 V 1991 D 1999
G 1976 O 1984 W 1992
H 1977 P 1985 X 1993
I 1978 Q 1986 Y 1994
J 1979 R 1987 Z 1995
K 1980 S 1988 A 1996
L 1981 T 1989 B 1997

Thanks. I didn't think Estes was making M motors yet.
