This figure came across my workbench recently for the simplest of upgrades: I slapped some LITKO FlexSteel on the bottom, so that it would be more secure when stored or transported in magnet-lined boxes.
As far as I can tell, this figure has never been featured on TMP before.
According to my records, it's a Dung Demon.
I did an online search, though, and could not identify a model by that name.
This is an older model, quite heavy, certainly a metal figure. I think the base, with its grassy texture, might also be cast metal.
Here's a size comparison with a standard 28mm figure.
My records include a date – 6 September 2005 – which is either the date it was completed or the date I acquired it.
Almost 20 years later, I have no recollection whether this model was a gift, if it was a commission, if I bought it in an online auction, or how it came into my collection. If you can identify this model, please comment; if you are the painter, please come forward for a bow!
