This photo (click here) is c. 1944 colour slide of a 2nd Bn Seaforth Highlanders of Canada F8 4x2 seen from the rear. It has the long box 1A2 body.
Photo of cargo box as found by original poster of this string LOOKS like a long box 1A2 8 Cwt one, not a 15 Cwt. Hard to tell from photo.
Unusual to find one of these bodies on a Cab 11 8 Cwt 4x2 . Cab 11 NORMALLY had a 1A1 body (short, huge tool bin/spare tire carrier, 9.00x13 tires, gas tanks across behind cab, NO step under doors due to lower tires)
8 Cwt 4x2 Cab 12 usually had long box (1A2) no tool bin behind cab, spare tire carried inside rear box, gas tanks mounted parallel to frame (fore and aft), and tires 9.00x16, AND A STEP UNDER THE CAB DOORS. I owned several Cab 12 F8 with long cargo box 1A2.
Note box found in junk yard does not match the 2A1 or 2B2 bodies
shown here.
IMPORTANT!!!!!!!!!
Scrape with sharp knife sideways, and and down by hand carefully for markings!!!!!!!
Being Cab 11, the UNIT NAME is PROBABLY painted in white on both doors near the top, above the DND number. There are variations in door markings so look at old photos. Sometimes name (e.g. a school) appears below DND number. Sometimes DND number will have a Z in front of or above DND number. Ficticious examples :
Z
_________
40-1-123
or 40-123

On one F8 I had, I found "IR OF C" (Irish Regiment of Canada) and under that, "HAL RIF" (Halifax Rifles).

YOU ONLY GET ONE CHANCE TO FIND ORIGINAL MARKINGS (and thus history) of a vehicle!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
