Hi Mark,
I’m not sure what chassis I have. Someone said it could be an ‘MSR’ built by a guy at the old Surbiton track, Neil Somebody. Circa 97. I have put some images on Flckr in case anyone has some more info on what it could be. Good news that I can run it with the torsion bars. Less work to get it ready 🙂
