These models are original, purchased in brick and mortar stores decades ago. They've been biding their time in various boxes and cupboards, moved from home to home, waiting to release the Waaagh!
I think I'm going to add a base to the buggy. Even though that's not how it was done back in the day, it makes sense to protect the model and make it blend in with the rest of the collection.
I still have another 20-30 Orks, another buggy, and an Ork Dreadnought tucked away. I'd like to get another Dreadnought to be able to build the second variant. Hopefully I can get around to adding them to the painted pile this year.
So far, I've been avoiding anything after the Book of the Astronomicon (1988). Apart from an Oldhammer Orc Shaman (Ork Psyker) and the prospect of converting some 'captured' Bullock Jet-Cycles, Landspeeders, or Vincent Blackshadow Bikes, there aren't a lot of options. It might be time to hunt for one of the old Battlewagon kits for a centerpiece and venture into the 1990-91 era of plastic arms for things like Madboyz and Stormboyz... hmm... I think have some of those original metal Ork jump packs around here somewhere. I still feel like the three Ork books fit into the Rogue Trader era, but the aesthetic of the models changed. There's a lot of variety in the originals so it will probably be fine, but I'll have to actually paint up a few to see (yes, I have a pile of those too).
