I've inherited a Black & Decker Whipper Snipper 350mm Line Trimmer model WS600. The unit is mains powered electric, and appears to be in working order, however it is missing the spool & cap. I am trying to identify what the part numbers are for a replacement spool cap and for the correct spool stock. I can't seem to find replacement parts listed anywhere, or the manual listed online, so I'm trying to locate either the replacement part numbers, the manual but it would be great to find both. Cheers, Paul
