I have a Model 10-8 with the serial number AYV65XX

With the brief research I have done, I do not see an "AYV" prefix in the smith numbering system for the Mod. 10

Does anyone have any information on this serial number?

AYV probably is 1987. I have a 3 inch 10-8 with ANDxxxx sn. The AND sequence is not listed specifically in the S&W Standard Catalog (2nd ed. anyway) as is the case with your AYV sn. I think we have to interpolate a bit and assume the missing letter combinations are in between those that are published. My take anyway, someone else may have a better answer.
