Which ones are you referring to (the thread has drifted a little)
No7 Mk1
CNo7 Mk1
No8 Mk1
N9
2000 No8's were manufactured specifically for NZby BSA, I seem to remember that these were sold off in a big auction in NZ a couple of years ago.
Never say never, but, I'm pretty sure that Savage bodies were not involved with any of these trainers.
