JoanK, I know something about Silvetons; PM me if you like.
Silverton and Ovation WERE part of the Luhrs family
, but have since been through a bankruptcy proceeding and purchased by the owners of Egg Harbor and several other higher-end brands.
FWIW, Luhrs, Hunter
, and Mainship were purchased by Marlow... and the Luhrs brand has since been spun off yet again.
