1:20.3 Scale Climax A Locomotive Poling Pocket, 4

Here we have F-scale poling pockets in the style of the Climax A Locomotive.  These are intended to be printed in detail plastic or stainless steel.  The design and mounting arrangement are described in Ed Hume's book, A Climax Class A Live Steam Locomotive, (ISBN 978154545404898).  The holes are sized for two #0-80 and one #3-48 hex head screws.  The #0-80 screws are separated vertically by 0.406 and the holes are separated horizontally by 0.422.  The outside of the plate is 0.688" x 0.563".  There is more information on the book and the author at http://Model-Shop.net.   The book shows photos of the pockets being made by silver soldering lathe-turned pieces into CNC-shaped plates.  Purchasing printed pockets is a convenient alternative.
