Well done I was wrong,it is in-fact a VC-Mustang S.The head I'm not too sure about as the number stamped on it is suppose to match up with the model number.However the 437 does match with the same time period VC-Mustangs so it could be.I'm just not 100% sure on it.Still trying to work out the documents I have on that,as they only started using those numbers from 1977,of which is the same year your mower was made.
So as I said before about worth even though it's not a common one (and I think that becomes the 4th one I know about) it's still not worth a great deal.I paid $25 for my one and another guy I know had his given to him,so there not worth great amounts.Some times rare doesn't mean expensive.Although I'd still like it.
