Louis...s/n is S192841, shipped on August 8, 1963 to J. S. Oshmans Sporting Goods in Houston, Texas. It is stamped MOD-29 in the yoke cut. Yours missed that manufacturing stip as dates to late 59 or early 60, but could have been shipped later as this one was. Most 44s were stamped MOD-29 after s/n S184000, but a few were not.
