Maybe this has been discussed before. Thru the decades, AC used different series of letters & numbers for their tractor models. I often wondered what processes evoked the radical changes(marketing scheme, competition, etc...?) Anyone on forum have first hand experience in these matters?
10-18, 15-30, 20-35
U, UC, WC, WF,
B, C,
WD, WD45, CA,, G
D14, D17, D19, D21
190, 180, 170, 210, 220
200, 185, 175
7030, 7050, 7040, 7060, 7080
7580, 8550, 7000
6080, 6060, 6070

The WC, WF,B&C need to be grouped with the WD WD 45. Each grouping was a major styling change and they did not carry on the modle designations for that styling group. It was marketing and no other reason for the changes. This of course is my opinion. I wasn't there, just a kid that went to the Allis dealer with dad a lot.

Most of the number series are pretty self explanatory, relating to their hp rating. Here's just a few to give you an idea. 10-18 = 10 drawbar, 18 belt. 20-35 = 20 drawbar, 35 belt.
D15 is 35 drawbar D17 is 47 drawbar
7010 is 110 pto 7050 is 150 pto
8030 is 130 pto 8070 is 170 pto
4W-220 and 305 are 220 and 305 engine hp, respectively.
Also...some tractors just morphed, like was already mentioned. In example, the WC became the WD, then WD45, then D17, then 170, then 175, then 6060. I think that's right. Someone will chime in if not.

Once the 7000 series production started and after is the only time the numbers made sense. The D series doesn't quite fit your line of reasoning Creston because of the drawbar rating for a D21 or a D19 or a D14 and a diesel version being different from a gasoline or LPG, then series II and III being different as far as the 21 and 15 are concerned but starting with the 7030 and 7050 in January of '73 at least something made sense.

If you look at the 'Serial Number Reference' summary on this Forum, I think you can see a simple progression of Model Designation using the Alphabet.
The 'A' came out in 1935, the 'B' in 1937, the 'C' in 1940 ,the 'CA' in 1950
In 1948 The WC became the WD, then the WD-45.
In 1957 the 'D' Series started with the D-14, then in 1958 joined by the D-17.
Then in 1959 the D-10 and D-12 , 1960 the D-15.

E and F? I know the E 15-30 and the E 18-30 and E 20-35 and E25-40 and E 30-60 were made in Wisconsin and there was an experimental D and F made in Wisconsin but now do tell more about the E and F made in England.

D Series - D was for "Dynamic" During the letter series, other manufacturers were using letters for their tractor models as well. D series was a transition to numbering.

'D' is a letter, not a number.

D is a letter but D17 has both a letter and numbers.

Gary. Read my post again LOL . When the D-14/17's were introduced, the literature headline was ' Dynamic" D-14 and D-17. Half letter and half number. Most manufacturers had letter designations for their models including A-C before the 50's . Throughout the 1950's manufacturers were all begain using numbers. D series was both. Thats my story and I'm going to stick with it ! LOL.
