I found it at a secondhand shop for the first time in 40 years, and although I only intended to make a simple version for a supporting role, I decided to put in a little extra effort. It might actually look pretty cool.
I painted the base black with water-based hobby paint so it would be easy to erase in a digital diorama, but then I wanted to try painting it with lacquer bronze, so I did a top coat. I thought water-based hobby paint was invincible once dry, but it turns out lacquer dissolves it... Haha... I didn't know that because I don't usually paint. After layering the coats, it ended up looking surprisingly subdued, so maybe this is okay too.
