Saving Old Seagulls

Thanks Oyster49 guess if original coil lasted 54 years cant be too unreliable!

hi have acquired 40 plus SJP with Villiers mk1 ignition with sparking fault will be picking engine up at weekend and will investigate problem assuming I may need secondary winding or re-magnetising can any one help with parts would it be more cost effective to upgrade to newer ignition/flywheel ...
