Difficult to read, the reg looks more like N739A than N738A and, while the latter was an S-55, it does not seem to have served with LA Airways. The 1950s LAX tower is seen and, together with the tail of Convair 880 N826TW which shows in the original photo, probably dates the photo in mid-1961 before the modern airport west of Sepulveda Boulevard opened. N739A was returned to Sikorsky in 1963 and sold to the Argentine navy. Photo from: Greg Gayden
