The US .
US springfield 1903 and M1 garand of WW2
Sorry- but a bayonet for WHAT? You told us the year, but not what rifle it is meant for.
Your inland made M-1 Carbine will sell for between 500-750 dollars,depemding on condition and a good bore.
its around $15-$20. There is no such thing as an M8A1 bayonet. The M8A1 is the designation of the scabbard that holds the M-4, M-5 (series), M-6, and M-7 bayonet.
$75 to $400 US depending on the condition.
i would say a couple hundred dollars
Value of ANY firearm is driven by exact make, model, condition, and originality. If you have a US Military issue M1 Carbine of good condition, they are selling for $600 and up. Depending on variant, the up can be significant. The civilian versions are typically about half that. You will need a hands-on assessment from someone that knows carbines. They were made by numerous companies, and have several variations (hi cut wood. low cut, flat bolt, round bolt, bayonet lug, etc etc.)
The value of M1 Garands is steadily climing. In good working condition, i would not sell one for less than $600 US.
$300 see ebay
