Well Hell, I didn't even see the assembly video first time around!
That's okay, I may just have enough engines to use them both, one in the house and one in the shop. If I don't have enough small engines to fill them both, I definitely have plenty of minerals, pocket watches, brass HO/HOn3 engines, arrowheads, assorted artifacts and who knows what all else, to fill a dozen or more of these things! Not that I actually have room anywhere to even put the one I just got!!! ;c)
