Preston's Guide

I am looking for a good price on a Preston’s Guide. Also does anyone know if the guide has been updated lately to cover years 1968- 2005 maybe. Current publication covers to 2000. Where can I buy new book at reasonable price???

Thanks
Charlie

Got a Carrier 58STA 135 101 – serial 4503A33232 – can’t find it in Preston’s 1960-2005 edition. Looking for the year. Help?

Occassionally, you find a unit in a house that’s a contractor’s special. This means that it was sold only to contractors for installation in a tract house in a large development or similar.

If it’s a Carrier, I’d guess that it was manufactured in 45th week of 2003. Just a blind guess.
