Australian Chevrolet WO database

I did read the R could also indicate a replacement engine, but engine number matches plate so that's out.

It's not R, it's PR3782449. Entirely normal for a Canadian-built original CMP engine, and the R in that does mean RHD.

Thanks, I do see the P before the R now. Any ideas on what the numbering stands for on this Holden tag on same Blitz?

WO49 is a GS truck, C60L (8443 chassis).

Referring to AWM126 vehicle registers, the engine number PR3782449 is close to those GS trucks (some with drop sides - D/S) found with ARNs around 60400 +. For example, engine number PR3782544 is ARN 60472, which has 'WO49' in the 8th column. ARN 60502 had engine number PR3782539. 60508 has '49' in col.8, and PR3782480 as the engine number.

Look at the GS trucks around those ARNs and you may find your vehicle.

The last image is of the plate attached to the front sheet metal. 'WO F End' means 'War Office Front End', along with the production number and date. All GMH manufactured CMP front ends were tagged in this way.

WO is War Office, and was the GMH descriptor for all CMP variants and major components, such as the front end sheet metal assembly. A WO number was assigned to each different vehicle design.
