From the Williamson factory prior to its closure many years ago ,all parts except casings some have slight surface rust.
offers around £250
Not sure if these are still for sale (ex-Tony Green presumably) - I need one or two parts (but not the whole lot!) - if I e-mail details and a photo of what I want, would you be able to help me?
Parts still with Tony Green so i am not sure what exactly is there ,it may be a idea to e mail Tony to see if he can assist.
