Yeah that's one of the rarer toys the troop transport... I reckon for sure that would have been put in by one of the guys in the mando production unit who had the toy as a kid.
Looks like they are gonna re-release it too: https://forbiddenplanet.com/297404-star-wars-the-mandalorian-imperial-troop-transport/?gclid=Cj0KCQjw9ZzzBRCKARIsANwXaeKciQSp1GFRwVETMLrcqfb-_0OyvHdTtj9w0oosHlqtZb7DScM1d38aAgsNEALw_wcB
The ones in the pic are the SW micro machine action fleet, they were produced from the mid to late 90s for the re-releases, and then started up production again for the prequels in the early 2000s.
The one that got away so to speak was Slave I, might have to see if I can pick it up on eBay one of these days.
The old B-wing was massive yeah, probably 60cm long. As a kid I would reenact the hoth battle using the OG ATAT and the action fleet snow speeder, they were just the right scale for each other.
