Thanks

Did they continue the letter system after 2004/5? I saw an indication/hint somewhere that it had changed.

PS(Monday AM): Just talked to York distributor. there has been a change…at least for Canada

Example: first 4 letters/digits of serial # W0B7XXXXXX

w- place of manufacture …W= Wichita
0- first digit of last 2 #'s of year code
B- month of year; B= Feb
7- last digit of last 2#'s of year code
X’s- six sequential #'s
This was made in Feb/07

See: http://www.usair-eng.com/pdfs/Serialnumber.pdf

The serial #(S)NFJM070423 seems to be the old version. Disregarding the (S)
N- place of manufacture…Norman
F- month of manufacture…June
J- year of manufacture…1979 or 2000
M- description of unit type, etc
and then 6 sequential #'s

I got off track by knowing a bit about there being a change…the 070423 #'s seemed like a regular explicit dating…07 = 2007; 04 = April; 23 = day
