I'm not sure Flatacraft ever produced a Manual as such, just a sales type brochure, and bearing in mind it's got to be @20yrs since any Force 3s were made you'll struggle to find one.
The last I heard all the Flatacraft specific spares had been brought up by the new owners of the Flatacraft name, but as they didn't make more than one or two poshed up Force 4s before going under again I wouldn't like to guess where they are.
Last time I spoke to Tony Lee Elliott who developed the Flatacrafts and owned the company, again years ago and after he'd stopped making them, I'm sure he said he had some Force 4 stuff left in stock.
