Are those klieg lights on that spit? I know they're not beer kegs
The filter was neccesary for desert ops, but added weight, drag and reduced top speed. Since the Spit V was struggling to keep up with the 109s and later 190s as it was, slowing down didnt help
Because of the dislike of that filter, there were locally modified Spits with a smaller filter. The Aussies took many of there Spit Vc Trops and took off the Vokes filter and hand bashed a cowling panel for the underside of the engine.
The Spit IX is carrying beer kegs btw. They were used to carry beer to the squadrons once they moved from England to France
