This is what I had to say about Shay drawings at the LivesteamShays yahoo group:
As for drawings, a large number of the original drawings for Shays still exist.
They are mainly located at the Califorinia State RR Museum (CSRM) and the Allen
County Historical Society Lima OH(ACHS).
The first step is to pick one of the Shays then order the drawing card index
(DCI), if the shop number is 3000 or grater then the master index from CSRM is
required. The DCI lists most of the drawings needed to build a Shay locomotive.
The plan number is usually listed in the DCI header. The paln drawing or
errecting drawing usually shows the frame from the top and the side view. The
early plan drawings also show the csoss section view at the engine. As Shays
were built to several gauges the cross section view was put on a seperate
supplimental end view, for the later plan drawings. The trucks and engine are
not shown on the plan drawing. There were never as far as I know assembly
drawings of the engines, these have to be assembled with the individual drawings
called for on the DCI. The trucks did have assembly drawings. The very early
truck plans seam to have disapeared or were upgraded to newer model trucks. This
route takes a lot of time and a bit of luck sometimes. I have been down this road a
few times so I might be able to help.
As for printed drawings of Class A Shays, one of the best articles was in MR
Sept 85. This is a Shay issue and has Allen J. Brewsters article titled "Baby
Shays". The drawings are very good and it is clear to me that Brewster used some
LLW prints. My drawing of S/N 181 was in the NG & Short Line Gazette in May/June
05. Check Message # 707 for the list of articles I have written for Steam in the
Garden. Several of them will be usefull for your project, and all are from
actual LLW prints.
