The North American Steamboat Modeller's Association (NASMA) was
formed in 1999 by two model steamboat enthusiasts. It was created to
serve as a friendly forum, by which steamboat modellers could share
ideas and construction tips, locate manufacturers and suppliers of
good quality products for steam modellers, not always an easy task in
the US apparently, and also present and exchange ideas on members’
current and future project ideas. NASMA publishes a newsletter four
times a year which provides a useful information exchange for its
members. Membership has been growing steadily and the group is
always interested in recruiting new members from all over North
America. For information on a subscription to the newsletter or just for
more information regarding NASMA and its aims, contact Steve
