Steve are you sure this is the complete model number?

Preston guide has a model number L78B84DC12 in 1992 through 1995.
Hope this helps.
Yes, that helps. I guess it would help to put all tne numbers in L78B84DC12-1
Thanks,

The last three letters of the serial number give you the date of manufacture:
B = month
N = year
A = place of manufacture
B = February
N = 1992
Thanks for the help
