Is there a reference publication that explains all the various Plymouth models? I see P-10, P-8, P-15, Q, etc, etc. When someone says he has a P-10, is that referring to the year or body style? Inquiring minds want to know. (I have an M-P-2-L-4) Thanks.
Those were the engineering codes for the car line. In the early days there was typically only one line in production at a time so generally the following is considered the correlation between year and engineering code:
1928 == Q
1929 == U
1930 == 30-U
1931 == PA
1932 == PB
Not really true as the Q was introduced in summer of 1928 and marketed as a 1929. However the U was introduced in 1929 so to keep the confusion down Q is considered 1928 now. Also the older line was sometimes continued, with reduced options, when a new line was started. So the are late PA cars that were built at the same time as the PB.
Starting in 1933 there typically was two lines the fancier one generally considered a DeLuxe the other a standard, business or Road King.
PC => 1933 New Plymouth 6 (early in the model year, replaced by the PD and PCXX later in the year)
PD => 1933 Plymouth DeLuxe 6
PCXX => 1933 Plymouth Standard 6
PE => 1934 DeLuxe
PF => 1934 Standard
PG => 1934 Business
PJ => 1935 Exception to generalizations. . . DeLuxe, business, etc. all share the same PJ engineering code
Things settled down in 1936 with two codes per year using numbers with the fancier one using the higher number:
P1 => 1936 "Six"
P2 => 1936 DeLuxe
P3 => 1937 Six
P4 => 1937 DeLuxe
etc.
Changed again in 1942 where there was one engineering code number with a couple of alphabetic suffixes:
P14S => 1942 DeLuxe Six (lower trim model)
P14C => 1942 Special DeLuxe Six (higher trim model)
There were different body styles each year which is independent of the engineering code (coupe, four door sedan, etc.)
All of the parts books I have and the factory service manuals list the correlation between engineering codes and model years, so that is where you'd go to get the information from original sources.
Well said :)
Thanks JoeT for asking the question, Thanks Tod for enlightening some of us that are not that familiar with these code. This is the first time I have seen these explained this good. I have figured most of these out over the years, but... Now I can print this out and put it where I can find it. Thanks Tod.

While you are on the subject do you have the codes for Pickup, commercial vehicles and cab and chassis?

I've only seen listings for "commercial" which include pickups. I don't think they broke out pickups, panel vans, cab & chassis separately.
1937 - PT50
1938 - PT57
1939 - PT81
1940 - PT105
1941 - PT125
