Vintage Lot of Insignia Pins

Lot of four vintage insignia pins. There is a TWA pin, a lapel pin I believe, and another in a gold eagle, one that looks like another type of pin that also makes me think airline, and the third says MW of LA on it with a maple leaf and a tool. The only one I recognize completely is the TWA pin and research did not help me identify the others so it's a mixed bunch I'm afraid. Would be good for costumes or uniforms to give an official look, and of course if you recognize one that would be wonderful.
The smallest is the gold eagle, and it measures just about 1/2 inch. The stick pin is the longest/largest and its 2" long.

Excellent vintage condition. Just some tarnish as befitting their age and use.

Please note: These are vintage, preworn and/or preloved items. I do my utmost best to list any issues, but signs of wear should be expected, and there are occasionally small things I won't deem worthy of note. Please feel free to send me a missive with any questions. I'm truly happy to help in any way possible and I'm always up for a chat.
