Post up some pics of your bike from all angles. There are some tell-tale modifications that were done on the bike by Colin Seeley that will stand out.
I must admit to always wondering why the ignition switch was relocated to inside the fairing, & I think that it may well have been something to do with the wiring.
Hi sorry can't photo the bike as suggested as it's stripped although i do have a couple of pics that i'll get up of it when it was complete. It's got all of the right bits on it to be a PR excluding the silencer, the ignition switch being in the wrong place, and it's been quite badly painted straight red. I'm also not sure about how Honda produced 150 bikes in the Honda Britain colours and then I believe produced a further 250 of them in either white and blue or white and red. I'm trying to establish, A is it a genuine PR rep, and B if so is it one of the 150 or one of the 250.
