Mike, if you are positive there is no script suffix as part of the serial number, then a so suffix block 1937 would be all blue (no strawed parts). The 1937 production started in the mid P-Block and continued past the Z-Block to the No Suffix, A-Block to the early B-Block. The best information that I have indicated the strawed parts were discontinued in the early T-Block. Hope this helps!
Secondly, if the pistol were reworked, I would think they would have blued all parts.
