Ral Partha Giant

I found this old model recently and decided to give it a makeover. I'm not sure where I got it from but it had been painted and based by another painter. Unfortunately the quality of the paint job was, well, poor (I'm being charitable, it is Christmas after all). The model also looked like it hadn't been varnished because pretty much every surface was chipped and bare metal showed through in several places. So I decided to strip it back to a clean surface and start over. So far I've only got as far as priming it but needless to say I'll post pictures of my progress when I finish. I made an interesting discovery while preparing the model. It had been based using some sort of clay material and I wanted to put it on a much larger plastic base. So I chipped some of the clay off and the last slab, covering the bottom of the base, came off in one chunk... revealing the makers date of 1977! This old fella pre-dates my introduction to D&D. I would have been 7 or 8 at the time this first hit the shelves.

I'll be painting him with reverence and when finished he'll get a special place for display. If anyone can identify the model further (Who sculpted it? Did it have a name?) I'd appreciate any information you can supply.
