I don't know anything about these bikes. But it might interest someone out there looking to add to his or her collection. 450cc. Looks all there. Olive drab.

I had a civvy one once, lovely comfortable ride, especially over rough ground, awkard to start because its one of those toe stubbers; clutch needs a complicated tool to dismantle it and the suspension rubbers are hard to find, at least they were when I had mine.

I liked it.

£900 I got for it

I've always fancied an F.N...(The Belgian BSA)...I have a particular fetish for the Tricar and the heavy military sidecar outfits built by them before the war..

I've had a close look over a few F.N.s and they seem to be a good quality machine...Spares availability (or lack of it) is what always stops me taking the plunge though...Ian.

my civvy one had miller electrics with coil ignition, worked well enough, Amal carb also.

I got bits from a British guy living in Liege, can't remember his name.

I see Bonhams haven't cottoned onto the the fact that the rear end is also under suspension.

Quite a good spec for the time consiering how many rigid/plunger bikes we had.

I liked mine, another one I wish I hadn't sold.
