The model 241 was made between 1935 and 1949. The "Speedmaster" designation was intruduced in 1936. There were approximately 7200 produced in the first year (1935). Your serial number is probably below 7200, therefore no Speedmaster will be on the receiver. You have a first year (1935) production gun
I have only seen 3 in my life,though Remington says they produced over 100,000.price range from $200,for standard in ok shape to $500+ for the elusive "EL" at the end of the model number that signifies expert make target gun.
Check the barrel and receiver
With Remington rifles and shotguns, age is not determined by serial number. It is determined by a 2 or 3 letter barrel code. Small letters, on the LEFT side of the barrel, just in front of the receiver. You may need a strong light/ magnifier. Once you find them, Google search for BLACKPOWDERX Remington. That should take you to the Remington Collectors Website, with the barrel code date tables. BLACKPOWDERX was the code used by Remington- B=1, L=2, A=3, etc.
Your Remington 1903-A3 was made by Remington in 1942.
