Howard guided them into the living room where his tools were sitting from working on Bucky's arm, which was sitting aside. "I'd only recently started learning about it. An old friend of mine has one, and it needed routine maintenance, so I started learning about it. Came in handy when two others showed up and needed one built from scratch. Working on a third now for the fella who's post you commented on," he said, nodding to the silver arm.
Once Ed's automail leg was exposed, Howard put on his microscopic glasses to see the detail, kneeling down to look it over. It definitely reminded him of Bucky's arm. Not the same scientist or inventor, clearly, but same gist. "Just looking for someone in case it needs maintenance?" he asked, out of curiosity.
