Does anybody know what this is?

I put up this question on the forums a few minutes ago and I'm here to cast another net to increase the chances of a successful catch. I’ve scoured the internet and I have found nothing about it except for a forum post on beyond the sprues from 2014. Here’s the link: https://beyondthesprues.com/Forum/index.php?topic=4931.0 I’m just confused on what it is, where it came from, and what aircraft carried it. If anyone can give me any information about it it’ll be appreciated.
