Theres is a stamp that says oklahoma Hwy Patrol. 9439?
Lots of .38/44s have similar stamps because most were sold to LE agencies. Consequently, unlike many other older revolvers, these marks don't seem to affect the value if they're period-correct.
Check my first post; I added some warning notes, and I just thought of another one!
A fair number of .38/44s can be found with the chambers lengthened to accept .357 Magnum cartridges. Your first instinct may be to exclaim "HOLY CARP, were they nuts?!?"
, but the conversion is usually (key word usually...
) fairly safe because these guns were designed to accept a cartridge that ran close to .357Mag pressures anyway. That said, I wouldn't fire .357Mag in a converted .38/44 today, because it's a valuable collector's piece and the risk isn't worth it IMHO.
FWIW the conversion doesn't seem to affect values much unless the gun is in a high condition grade, and this one isn't.
