This is the Wikipedia quote..
Andrew Barclay Sons & Co. are a builder of
steam and later
fireless and
diesel locomotives. The company's history dates to foundation of an engineering workshop in 1840 in
Kilmarnock, Scotland.
After a long period of operation the company was acquired by the Hunslet group in 1972 and renamed
Hunslet-Barclay
The cab is stretched and the body designed to fit a Hornby Pug chassis which will only need slightly modifying.
