No there shouldn't be a cut in the ring.I'm not sure on what colour they should be as I haven't got that far yet.I mean I haven't started restoring them yet as I have about 10 mowers that I started but have had to put them on hold or this [Censored] move.So sorry I can't help there yet.I usually take to a sample to a paint shop here in Fyswick there is a young bloke there who colours matches for me.So far he has been spot on.
