The above 4", 4 screw, blue, pre 29 was ordered out of Kansas as one of a special ordered pair of consecutive serial numbered 44s. I just got a letter saying I had the other one of the pair. Lemme know.
Per the information I have on a shared database S 170363 pre 29 4” was shipped July 1957.
No further information was available on its whereabouts.
Good luck on your search and best regards.
Jake
