Spingfield 1903 mk1

I want to replace the WW2 replacement parts of my mk1 with correct 1919-1920 parts. Where can I get information as to what those parts would look like as opposed to parts from other eras? Parts I know are wrong at this time"
striker, bolt sleave. cutoff, stacking swivel. Possible wrong parts are; rear sight ladder and slide, trigger, front band and stock. The stock is from the right era but it is not a mk1 stock.

i have some Mark1 parts, though not cheap.
might want to try the Jouster want to buy
