Vintage circa 1920-1945 no date code buying war time production Snap-on Tools M-10-DG war finish obsolete 9/32 mini breaker bar

Did quite a bit of research to come to the conclusion about this Snap-on Tools breaker bar. Here is my buying best effort: there is no date code so possible it pre-dates date codes It is a 9/32 breaker bar ratchet model M-10-DG. This is an obsolete tool these days unless you have sockets in 9/32. Has a war finish which is more satin rather than the more common polished finish. Has the latest patent no. To 1940 Measures 6 1/8"
