Receiver stamp 1903/A3?

[butlersrangers]

The O.P. seems to have a 1903 receiver that a hobbyist altered and re-stamped to look somewhat like a M-1903A3 receiver.

An '03A3 stock, hand-guard, and barrel made into a 'shooter', using a (Springfield, Rock Island, or Remington) 1903 receiver, barrel bands, and trigger-guard?
