It's something I have said before and thankfully can keep saying: There is still so much more material to publish on this website. So thanks to Akiko, I dug up this Owner's manual for a Honda CL77. And, also as usual, more soon!
Williamson Sports Motors later apparently became G. Brick Motorsports and the phone number stayed mainly the same. The number only changed from 717-726-3343 to 570-726-3343. Seeing that the domainname has expired as well as the building this company once sold beautiful motorbikes from looks quite empty, I can assume that this company is no more.
