This westinghouse radio prop has been posted before but I was looking at the Star Trek 365 book and noticed a pic from The Alternative Factor. There is a lamp sticking out of an Engineering control panel that I thought looked familiar...
Good one. Dagger was produced before Alternative Factor so it was already a reuse. In fact it looks like they re-used the whole control panel. I can see it originally being added as a mic for the first use but it looked out of place in engineering.
