New World bike E55712 is a standard men's frame, dark red example. It looks to be in the 1948-49 date range, based on your chart. It has:
Electro-forged bottom bracket shell
Standard pitch drive train
One piece crank
Mesinger Slide rail saddle (the balloon style one)
Standard type post-war fender braces
Front and rear hand brakes - "Schwinn Built" calipers with Schwinn type levers
Dunlop EA1 / 26 x 1-1/4 stainless rims
British-style wing nut front hub
December 1948 Sturmey Archer AM medium ratio 3-speed hub
Galvanized spokes
Hockey stick chain guard
Chain guard has the brake cable housing loop for the Schinn unisex rear brake routing
standard New World round head badge
This is the first New World I've found with British clubman style wheels. I thought they were 1960s replacements originally, but then I noticed the 1948 AM medium ratio hub and the old-style Dunlop stainless rim imprints. The wing nut front hub is another odd addition. So perhaps someone special ordered a somewhat sportier New World. Kind of strange to stick to the one-piece crank with all that though.
The bike also has the best preserved set of Uniroyal chain treads I've ever seen on a 3 speed bike. They were nice tires, but nylon cord, so probably somewhat after the bike was made.
