the 44 is a 44 Hand Ejector. 2nd Model , made 1915-1940, SN range is 153xx thru 59xxx with about 17K made. Those are 1920's factory grips and the sn 22000 is indicated as 1925
the 38 Safety Hammerless 5th model - should be 38 S&W (not 38 special) was made 1907 - 1940 with some 40K made in range 220000 - 261493 so yours is later in the range, probably from the 1930's
one question is whether the barrel length on the .38 is factory or not. There were some reported in your SN range - if factory letter verifies it, adds quite a premium to the gun..
couple nice guns - the 44 is always a favorite with S&W guys - and that 38 looks sweet, factory barrel or not !
