I am making slow progress on working out how to find Lima Shay documents at CSRM, I found out how to search for the source record id which is the unique identity number. I was correct the DCI records are in sequence so this will help to find all of them in the CSRM collection.
I went backward with the identification number and found a mixed bag of drawings with no obvious reason to be in a continuous block. Then I spotted a Shay card redrawn in 2005 which really got my attention.

Well, I know this drawing came to me in two parts with card number 231. Both parts have the file in drawer number so the drawing was damaged at the loco works way before it was at CSRM.
I took extra care to redraw this card with the closest I could get to the original fonts and all the notes.
I gave a copy of the restored drawing to CSRM on my next visit and never knew anything else about it. The old number could be seen through the blackout used to cover it and I kept that visible so it became the drawing number.
The small section of the drawing and my restored version are attached. If you look at the top the original draftsman is L.E.F 10/16/93 I simply added Redrawn 3/24/2004 D.G.R.
