Great looking sleigh, Paul,
If you have the Holiday 2009 issue #37 of Scrollsaw Woodworking and Crafts, there
is a horse drawn sleigh in there. The horse is abt 9 3/4" Long.
If you do NOT have that magazine, I don't think it would take me long to make a
similar version from a silhouette or clip-art. Just let me know if you would like a
particular stance (Can't promise but, will definitely try to make it to your liking)
and let me know about how long it should be to be in a good proportion to the sleigh.
God Bless! Spirithorse
