'DeadMan's handle' for MacCullough chainsaw in Scotland ?

Can someone please let me know any stockists in Scotland ( around Inverness /Dingwall or in the Central Belt ) where I can get the part(s) to repair the deaman's handle (safety bar) for my MacCullough 335.

Better still,I'm in the central belt at the end of Oct for a few days and could bring the thing down for anyone who could repair it
