    Unknown part identification

    Agree ^. Looks like a 2-in-1 1911 tool; removing / installing barrel bushing and main spring housing pin. Not sure the "U" shape part has any role.

    Road testing the small fixture plate with fabricated V-block for small parts tinkering. A Brownells #4 blank screw cross-drilled with short machine screw length #55 bit (0.052" dia). The v-block atop the fixture plate is really rigid and allows nice access to get at the small parts with...
