Spitfire 21 Engineering Drawing

Making a 3D model for sim use and I’m wondering if anyone has the line drawings for the 2-stage Griffon Aero Vee filter? The specific sheet is 35638 Sheet 33 from the F Mk 21 drawings (or 38838 Sheet 11 from the Seafire 46 set). I have the line drawings for the engine cowl but not the filter!

Additionally, if there are any drawings available for the F Mk 21 through 24 wing they’d be most appreciated; I only have the drawing for the extended wingtip leading edge and nav light. I believe much of the Mk IV drawings (of which I have many) actually apply to the Mk XX/prototype 21, such as the landing gear and radiators, but some further clarity would be helpful.
