I have a Clarissa by Polverini Bros E100 EL. The P in the name is kind of odd so I can see why many have said it's by Olverini. Mine is a kind of Ovation copy with a plastic dome back. I bought it in about 1985 from Holiday Music in Leytonstone UK. I can't remember how much it was. Quite a nice sounding guitar but the action is high and makes my hand ache after a while. I've used it live and have done some recording with it. The pickup packed up a few years back and I found a replacement, sorry I can't remember where I got it.
