Hello Chris,I can't even think in the dimensions that you use or the fineness of the work. My good lady makes bobbin lace that does my head in for fineness ,skill and complexity.
Richard's description of the light is spot on.They were made by Lucas and common to many British vehicles, they were also fitted to the Australian made ACCO trucks and I had heard them referred to as "Butler"in that context. Richard is more likely to be correct than I.
My parts book says they are a Convoy/dashboard light,definitely fitted to the RH mudguard (offside)above the number plate.The Sankey trailer chassis included the mudguards in the build, the other uses(cargo body,water chiller,water tanker,generator) were added as a separate construction,all are attached between the mudguards and so present the same mudguard configuration.
Richard,the piece of steel that you can see in the pic I believe was added on by a previous owner as it had a length of chain attached and I presumed it was to hold the tailgate in a horizontal position.There is nothing in any of the publications or other pics that I have had that show any thing similar,the locking catches on the tailgate hold it in the vertical down position.
regards, Robert
