Source of drawings

[Chris_Prior]

Hi everyone
I am looking for a source of drawings for GWR diagram E157  (Non corridor Brake Composite)
I need a pair of these for my Princetown layout and cannot find any r-t-r items, so I would like to scratch build (or maybe 3d print). However, I cannot find a source of the drawings. Does anyone know of a book or source?  I have tried the NRM, GWR archives and anything else Mr Google suggests, without really finding anything. I am reluctant to buy a book without knowing it contains the requisite drawing.
Many thanks for any help/pointers.

Have you checked this list of drawings?

I have looked at that list. They are all LNER items but the one I need is GWR. Thanks for the suggestion, though.

Perhaps the Great Western Society at Didcot might be able to assist.  The HMRS has company 'Stewards', possibly that might be helpful.  Or, perhaps, a request for assistance in Model Railway Journal.

With best wishes
