WD Poll Quad with bogies

Combination pack of WD poll wagon (quad bolster) with 2 pairs of bogies similar to Graham Farish diamond frames (11mm WB, = 5'9" in 2mm) and suitable for N-gauge axles (the pinpoint bearing cones will probably need careful reaming out with very fine drills to get the wheels rotating freely. One pair has fixed rapido shaped couplers at one end and pockets for short NEM couplings on the other end. The other pair is the same but with pockets for standard NEM couplings instead of short. Choose the couplings you want and cut off whatever you do not want on those bogies. Keep the other pair of bogies as spare for another project. 
UPDATE 2021-08-01: Added the same bogies as for the NER quad. The previous ones were a bit short on coupling length.
