Whilst Panthers were exported, Panther hunting is likely to be most
successful in the UK. I would start my Panther safari by joining the The
Panther Owners Club and looking at the classified adverts in the club
magazine (The Sloper). The second place I would look would be the pages
of "Old Bike Mart", a UK monthly newspaper which usually has three or four
Panther adverts, both private and dealer, each month.
How long's a piece of string? A very rough guide for reasonable running
condition for the more common models would be about 1500 GB Pounds for
a postwar four-stroke lightweight and 2000 GB Pounds for a postwar heavyweight.
Variation of plus or minus 500 GB Pounds, depending on condition, would
not be unreasonable. Two-strokes, I don't know, but they are not, generally,
highly sought after! Pre-war models I can't really comment on.
Spares for the postwar heavyweights are in reasonable supply. A few items, specifically cylinder heads, exhaust rockers and main-stands are, I believe, scarce. The Panther Owners Club remanufactures many parts and has an excellent spares scheme. Export of spares is somewhat problematic, especially to the USA and Canada as a result of those countries' over-the-top liability legislation.
Spares for the postwar lightweights are a bit patchier but generally OK. Again The Panther Owners Club spares scheme or M.Rayner are good places to start. A number of parts are very difficult to find.
Electrics are pretty standard being Lucas (on later models and Miller earlier). Gearboxes and clutches are Burman (Draganfly M/Cs, UK, who specialise in Ariel also stock Burman parts as they were used on Ariels, as well as several other marques; be sure to state that the parts are for a Panther since there are differences - special bushes etc.!). Carbs are Amal.
