Just pulling your plonker mate.
I can't think how it can be used with chalk though?. I guess there must be a way,

It was used on the molds that makes the toys so you rolled it by hand over the mold and the chalk showed the high/low points which showed that the mold has a raised/lowered edge so was not flat. The way it was discribed to me made perfect sense

There is a lot of truth in what tjlglass is saying.

I once worked in the petro-chemical industry by making control units, fuse protection units, safe rerouting control units etc, etc. All this stuff was sent to oil platforms, oil refinery plants and the like, so it was designed and made to international 'ISO' standards. Part of our testing equipment consisted of a wooden box,
very similar to the one shown, but very shallow and when opened, about five rows of ten tiny little 'tomb stones' were resting their backs on wooden supports.

What they were designed for is almost indentical to what tjlglass is saying, testing the trueness of dies and mould mating surfaces. In 'my' set, they were all made of the highest quality steel in a range of sizes. The thinnest could have been no more than a couple of millimeters thick, upto an inch thick. They were kept in their wooden case at all times and if you left one out on a worktop surface, you can expect the full wrath of the boss, because the set was rather expensive.

The interesting thing about this particular set, was that it was made by Rolls-Royce in their Metallurgy department and shown to me because of my interest in all aspects of R-R. I never used the set for my particular job, they were only used by the testing dept, but they were happy for me to see it.

It is fairly common knowledge that Rolls-Royce have one of the best metallurgy departments in the World and make some of the top branded golf clubs and hip replacement parts and I would not be at all surprised if they made the Lesney roller.

I'm relieved, it wasn't "an over polished Jobby"

The things you are describing are called slip gauges

I have never seen anything like this in the toolroom or foundry,to check for flatness you would use a straight edge ,and dies aren,t flat ,parts of it are but it would be a bit worrying rolling this beast around impressions,to me it looks like a roller from a coveyor,its possible someone found a use for it has a birmingham screw driver or another use in the toolroom,and the blue chalk?,i heard /used engineers paste which is blue and french chalk for marking out but not blue chalk.
I,m not doubting your mans usage or where it came from just puzzled,and loving this thread.I hope paul carr has the answer.
