Special request for Information on this Seeley Suzuki TR500

Rob Payne writes in with a special request for info on what I think may be an ultra rare Seeley framed Suzuki.  Can anyone help shed some light on this interesting ride?

He Writes in:
I have recently aquired a factory Seeley framed TR500 I friend has owned for 15 years. I have attached a photo of the bike just to show you.... I am basically in the process of restoring and also sourcing info on how many are left, how many were made, etc etc. I am told a factory cs seeley with original motor (TR 500 - 10077) frame cs 262S MK 3CS107N are very rare.Thanks,
Rob

And in a second message:


I have a bunch of other photos and historical info on the bike. I am trying to contact Colin Seeley and give him the numbers, but cannot find an email for him. I honestly believe, from what I am told and read online, that there are only maybe 3-6 left, if that. Please let me know if you can find any further info or get any feedback.
