[Graham Boak]

If you are still interested, there is a more recent and generally superior model of the Merlin Halifax produced by Revell itself (not a reboxing of the Matchbox). This includes a set of the Mk.V undercarriage (although undescribed in the instructions).

It is fair to add that the engine cowlings and propellers are oversize and require replacing. Those of the Matchbox kit require considerable reworking but are salvageable. There are a lot of faults with both kits but the Revell one is generally superior. You may not be concerned about these faults anyway.
