Vickers 3 Inch Quick Firing AA. 1/144 scale. These AA guns were used as the main armament on several Canadian Vessels, HMCS Mackenzie, HMCS Saskatchewan, HMCS Yukon, HMCS Qu'Appelle, and RN Tiger Class Cruisers. This is the later version with the single observation position. Care must be taken when removing the parts from the sprue. Recomendations and tips on finishing can be found in the forum. Recommended for experienced model makers. Due to the small size of the parts, this set is only available in the FUD and FXD material.
