Hello,
Does anyone know of any readily available sets to convert AFV Club’s Churchill to a Mk I / II? Inside the Armour is no longer producing from what I understand. Is IMA still in business/producing? I haven’t had luck contacting them. Any help is appreciated.

Have you looked here?

Might have something you are looking for.

Oops most all of their stuff for Tamiya kit , but on the bigger ones they give you the parts needed.

I’ll give them a look. Thank you!
