Okay Dan, it’s all your fault, you just caused me to remember things from 40 years ago! (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)
Knight statue figure looks for all the world like one which came in a plastic snap-together castle playset my little brother received for one Christmas in the 1970s. Had a several inch high square base molded in tan styrene to look like boulders, walls were light grey, roof color is not remembered. Had several standing and several mounted knights. Was actually a quite nice playset.
Will send him url for the page and see what Wes thinks of figure.
1st Edit: done.
And I very much remember the tactile sensation of point on helmet visor and feeling of shield surface with hand molding on back.
I don’t much remember configuration of castle though. Am certain it had actual chain for drawbridge.
And had a well.
2nd Edit: Found something about it, and there’s the guy!
