Has anyone updated the Rogers dating guide? The most recent guide I have is from around the year 2000 with the research having been done by Kelly Smith in the 805 area code (CA) and was apparently published in the Rogers book by Rob Cook.
In particular is shows 1965 and 1966 drum both having serial numbers in the 52xxx-59xxx range. I'm thinking that someone may have adjusted that by now.
Ploughman???
