That front post with the lower bar being brazed and l am pretty sure that's leaded to make smooth. Lead is most likely why the paint fails on these types of jointing methods, it oxidizes or whatever as microscopic stuff grows on old lead when any moisture has gotten to it.. It would be mainly used over brass brazing to make the joint smooth and otherwise looks correct. Or rather, in girl's I have a 48-9 and the center bar in-between top and lower are brazed and smooth. The upper stays are also brazed to the seat post.
On pre-war lower rear stays are straight, yours are curved, that's a sure sign of post war bike. Additionally, the fork's shoulders are just like Schwinn's. Pre-war is similar except the shoulders have bumps on em, like 'Sholder pads' You can just about see this on mrg's examples that also have straight rear stays. They also have, in front, a little molded-in extension for a fender screw mount.
That rear drop-out is also a post war feature, I think before 1948.
Yet that brazed on bottom bracket, that's pretty odd for a 46 but, whelp, the danged frame is odd to.
I also have the same 41 girl's bike mrg shows but house painted many, many years ago: ears, shoulder pads peaked fenders, straight fender brackets and a ladies seat except for one weird thing. The danged serial numbers make no sense at all. A few numbers couple of letters and jumbled like nobody's ever seen.
However, for an old interview where he was bragging about having more than 100 different badges on his desktop; I think; The CWC dude was like the mad hatter or a kid in a candy store, tossing all kinds of different things together, mixing paint colors and styles, head badges, old parts on new, U name it so, in some cases, U just never know why or what he'd toss up and hit the floor. .
I mean, all those badges, I expect he'd make them for anybody who walked in the door to buy a package of bikes to be made.
Potentially this frame may have been designed earlier but shelved pre-war or during WWII and for the 1946 date, revisited with post war materials.
