The National 2½" Gauge Association Keeping the spirit of the past alive and looking to the future.
JR and BS Drawings available from the Association
The Association has acquired a large number of prints (blueprints in some cases) of these drawings and
copies can be made for members use. Many of the blueprints have been converted and cleaned up (ie to
remove tear and other blemish marks) to create reasonable quality copies.
The JR Series
These drawings were produced by Jackson-Rigby Engineering Co. Ltd. of Station Road, Shalford, Surrey
for Henry Greenly.

The BS Series
After Bonds Ltd. took over the JR drawings, they were updated and renumbered with a BS prefix.
Later on in the middle 1930s additional drawings were made for such locomotives as the LMS Duchess, LMS 5MT 4-6-0 and LMS style 4-6-0. These later drawings (B.S.400-) were signed by G. Layton.
