Original factory dieline drawing

[tjlglass]

Just found this while going through some of my old books, it was inside the pages and got this from a former employee many moons ago, love these old drawings, I have a few of these somewhere but why is this one inverted (mirror image) ? I've no idea but think I might frame this one as it's wasted not being on display. Also has a signature on it, not sure if it's Jack Odell ?

Cheers Kev, why would this be inverted ?

Cheers Kev, why would this be inverted ?

Technical drawings used to be made on a tough, transparent paper and were then reproduced photographically. My guess would be that the copier at Lesney required the original to be inserted into the copier reversed in order to produce copies the right way round. However, one day, someone simply forgot, resulting in the drawing you now have..

Another question: what was planned there?

Looks like the Leyland Ergomatic Cab... but the second window looks larger and it has 3 axles.

I believe what you have there is the master technical drawing on translucent paper (as Hugh mentioned) This drawing would have then been placed face down onto chemically treated photo reactive blueprint paper and exposed to UV light. The end result, being a blueprint copy of the drawing, with a dark background,where the light passed through and white lines appearing, where the light was blocked by the original drawings lines, all turned the right way around. The blueprint would then be washed, to keep the white lines of the drawing, from exposing any further.
