This set contains accurate resin mainwheels with smooth tires, detailed hubs, and fine tire beading. Block tread tires were common among post war Avro Lancasters. They are not appropriate for wartime aircraft, unless you just like the look better. An easy and very noticeable upgrade for the new tool Airfix Avro Lancaster kits, but can also be fit to the Revell, Hasegawa and other 1\72 Avro Lancaster kits. Designed by Mike Swinburne. (designed to be used with Airfix and Revell kits)[B.I B.III]
