Knock, Knock. Who's there?

Whilst painting up some graveyard scenery last week for my RPG game (the sepulchre is visible in the previous post) I did a quick paintjob on an old Frankenstein mini that had been sitting on the shelf for a few years. My (poor) memory seems to think that is was a ebay purchase listed as an old Foundry figure, but the sculpt is pretty rough by usual Foundry standards (the hands and sleeves are the very basic) so I'm having second thoughts. There were no manufacturer marks on the figure base before he was glued to the plastic one you see in the picture. Can anyone help?
