Pre-27 barrel markings- fix or leave alone?

Curious

Congratulations on the acquisition of a very nice and fairly early postwar short action .357 Magnum. June 1950 sounds right.

The first postwar .357 Magnum, serial number S71642, was shipped on 12/05/46. This gun was a long action "Transitional" using many pre-war parts, but with the new hammer block safety and micrometer-click rear sight. Several more of these long action "Transitionals" were shipped in 1947, with most of them being shipped in 1948 and a couple more in 1949. Most of the known early postwar "Transitional" .357 Magnums were in the S71XXX serial number range with a few in the S72XXX range. The last known postwar "Transitional" .357 Magnum shipment was in March 1949. These guns, a total of approximately 142, were all manufactured at the old S&W plant on Stockbridge Street in downtown Springfield.

Production of the new short action .357 Magnum began at the new S&W plant on Roosevelt Avenue on the east side of Springfield with serial numbers S75514, S75515, S75516, S75517, S75519, and S75520 which were all shipped to Evaluators LTD, Quantico, VA on 11/18/49.

That is interesting information about the early production 357 magnums, I wonder what configuration #S75518 was, I own an early 357 magnum # S75523 (3 1/2" Blue) that letters to San Antonio, Texas Jan. 1950 I have posted photos before.
Like I said "Just curious"
