Yes is the answer to your question. The first shipment of 44 Magnums (Pre-29) to H. H. Harris was on March 18, 1958. S&W's records show approximately 120 Pre-29s with a 5-inch barrel were shipped. The first 5-inch barrel, S153748, was shipped on July 20, 1956. It has a 5-screw frame and is the only one known. It has not been reported by collectors. Three were shipped in 1957 and one, S170040, was Class A-engraved by Russ Smith (only 5-inch that is factory engraved, see photo below). The Model 29-1 and -2 were generally shipped in 1963. The total number of 44 Magnums with a 5-inch barrel is estimated at approximately 300 with H. H. Harris receiving 217 of them from 1958-1963 (very few were shipped from 1959-1962).
