PBR Caliper colour

One thing I have noticed with all my 1973 calipers is they seem to be painted a red brown colour.
I have checked all my 1973 calipers and they are all the same.
Melbourne or Brisbane same red brown.
If you check the photo you will see the witness of the surface finish.
All my 1971 and 1972 calipers are in natural steal.

Harness decals

Rear wiring harness tape flag. Width 31mm Length 74 mm.
These have a white background with black lettering.
They appear to have come of a tape dispenser with a serration on each end. Witch i suspect was on the dispenser.
This is located on the rear tail light loom on the RH side inside the boot aprox 140mm from the connection.Towards the beaver tail.
Point of interest here is that Melbourne cars i have seen use a vynal tape.
Sydney cars i have seen use a cellophane type tape.
Brisbane cars I have seen use cellophane tape as well. I suspect we will never know it all.

Diff HQ holden 12/1972 V8

Here is a photo of the date code on a V8 Holden Salisbury diff.
The number is located on the top side of the diff center.
There is also a part number on the housing it was stamped in paint and was do do with the manufacturing process.

Date codes 12/1972 SS

This HQ SS has original wheel to the best of my knowledge,the rims are the early Canadian type. Next to the valve stem is a series of numbers. They appear to be 9/72 RIMS.
There are other letters and numbers however i have not idea yet to there meaning.
The Canadian wheels are painted grey on the rear side, they also are spot welded unlike the Australian wheel which is stitched welded. The face of the Canadian wheel is slightly different to the Australian wheel.
I would say the outside paint would be 350 silver and 350 grey as normal.
There are also some photos of the masking template we made this is far better then the mask out kits, faster and cheaper and will last a life time, and will help save on land fill.
