According to the Air Ministry list the Dunlop tail wheel A.H.O. 5007/2 was in use for the Typhoon, Tempest, Whirlwind and Lysander with the anti-shimmy 5.50-4 tyre. It is possible it could be used with the Bristol Blencheim Mk.V. The tyre WL 30 was usually fitted to the Blenheim and Typhoon. The DH Mosquito tail wheel was of the Dunlop-Marstrand 8.00 × 5 twin-track tyre and the wheel hub marking was AH10191. The tail fork also doesn't look like the Mosquito one. It is too "delicate". Also I got an impression the "fork" was modified by cutting or breaking off. See the bottom pic. IMHO it is from the Hawker Typhoon.
