Hi,
As a comment for those that had not seen the collection, I have copies of the drawings that are DSP&P/DL&G/UPD&G. Same for RGS and F&CC.
So some could very welll be ex-D&RGW but some are not.
So this muddies up the waters even more.
One drawing that I am thinking of is of 2-8-0s on the DSP&S with a line drawing of a 2-8-0 and the dimensions are A, B, C,and so forth.
I would expect some drawings (maybe the majority) are direct copies of official documents. Others I suspect are new to Maxwell.
