I like this series as the size of the building is big so you can use them not just with your 1/144 kits, but also with the 1/144 Gundam figures. As you can see from the picture on the left, they are very useful if you want to build a Gundam diorama. More pictures can be found here.
And the answer to yesterday's question. Yes, it's a Chieftain Mk 5. Seems not a difficult question. Anyway, the kit is far from finished as there are quite a few bubbles so a lot of work need to be done.
It looks the gun is a bit too long. I haven't compared to the data so just looking at it, the gun seems too long to me. Whay do you think?
