Hi,
This Sandringham Six looks like the vehicle that I owned for some time.
Originally brought new into Ireland by Geological Survey of Ireland. (Was very expensive)
RHD but with speedo in Kms
Original Irish registration 1981 = 918 YZ0
The screw holes below the near side headlamp is where I had a small black perspex reg plate placed
Had large canvass cover over the back body when purchased
I bought it as a toy with a genuine 17,000Kms recorded
Drove it to the UK by ferry and sold it to Keith Gott, LR Specialists who said he had a Landscaper who was interested in buying
Best wishes with your rebuild
Geoffrey D
