Armour Plate Wagon 55t

Similar to the 40t armour plate wagons, but longer overall, and with longer wheelbase bogies. Modelled with BR style solebar detail, oval buffers, planked floor, and bogies with tie bars. Again, the couplings will lift and fall if washed carefully (never force them) and once free they can be return-sprung (if you like) from above with shims of thin clear supermarket packaging material cut to size and slipped into the pockets. Exactly correct wheels for N-gauge could be my 3D printed 2'9" 3 hole disc, but Parkside Dundas/Romford ones from 5.5mm to 6.1mm diameter should be OK. There's a pair of notches protruding from the undersides of the solebars just behind the bufferbeams at each end, to help locate brake handwheels mounted on fine wire. I have the CAD for the detail differences for the LMS and LNER built variants if you would prefer those.  Please see the notes on the 40t amour plate truck in case I've missed repeating anything  here.  FOR SALE WHEN I HAVE TRIED ONE MYSELF.
UPDATE 2021-07-16 Finally offered for sale, sorry I forgot to change it for so long.
The LMS solebar detail one is already available, and the LNER one is likely to follow quite soon (you'll find it very hard to tell the difference, though). 
More wibble about couplings: 
Please note that the couplings are printed in a half-raised position (oo-er) but should become free to move when the wax is cleaned out of the narrow clearances with warm soapy water, or an organic solvent. If you break the lifting ones, you can still use the NEM pocket (unless you have already cut that off) but those need care too.  NEM fitting rapido-style couplings are different sizes (so much for "standards"). If they're too big they will break the pockets unless you file them down first, and if they're too small they will not stay in unless you glue them, which defeats the intention that they should lift and fall.
