The product portfolio of MARK I Ltd. has recently expanded and now also includes MARK I Accessories – resin detailing parts and display bases for model kits in 1:72nd and 1:144th scale. While the former contain various details to improve or refine basic plastic models (e.g., external stores, vacu canopies, seats), the latter include pasteboard cards depicting various actual surfaces of military airfields (concrete panels, asphalt taxiways, helipads, grass). Due to their generic nature, they can also be used for kits in other scales (1:76, 1:87 etc.).
