Old Crow Models have sold the Ainsty range of vehicles and terrain to another party.
From their website:
As of the 1st of February 2011, Old Crow Models no longer owns the Ainsty ranges. They have been sold to another trader who will be relaunching them soon. Once details have been finalised, a link to his website will be posted here.
Thank you to all of you who have supported the Ainsty products under the Old Crow banner. We wish the new owner well for the future.
