Aspera clockwork engine starter?
First one I showed seemed to be a Briggs type, this looks older to me and workings look closer to Asper/Tecumseh etc. in style, see what you think.
Yes, may be off an old Victa or even a Mountfield
Thanks for the helpful replies people.
Kirby Lauson engine from Victa Corvette or similar . Right colour. I think I chucked mine as the cup part broke up.
