M3 Scout Car speed (various OOBs)

[Griefbringer]

By coincidence, I noticed that M3 scout car (aka White scout car) seems to have different speed (either 21 or 27) depending on OOB. I managed to find the following cases:

* Speed 27
- USA (OOB 12): units 133 and 378
- Soviet Union (OOB 11): unit 092
- Canada (OOB 30): unit 008
- Netherlands (OOB 29): unit 318
- Polish LWP (OOB 09): unit 046
- Nationalist China (OOB 21): unit 312

* Speed 21
- USMC (OOB 13): unit 104
- France (OOB 06): units 069 and 319
- Great Britain (OOB 07): unit 179
- ANZAC (OOB 15): unit 005
- India (OOB 18): unit 006
- Poland (OOB 02): unit 066
- Czechoslavakia (OOB 37): unit 145
- Nationalist China (OOB 21): 268

(Notice that Nationalist China appears in both lists.)

Whether the proper speed should be 21 or 27, I do not know, but I guess it should be the same for all OOBs.
