Eric, here's a link to a GunsAmerica listing for one of the Stoeger .22 Lugers, for your inspection. According to the description, it has raised letters for safe and fire--opposed to red and green painted holes, and this, along with the wear evident on the right, rear and upper corners of the toggle ears--which reveals the material beneath, this is one of the early cast aluminum alloy models.
