For Tamiya kit. This is the first in a series of  upgrade sets to correct and detail the old Tamiya Chieftain kit for Mks.1 to 9 (excluding Mk.4), ie. all of the non-Stillbrew Chieftains. With Takom having stopped production of their Chieftains, the Meng Mk.10 kit is the only other option.
The Tamiya kit is basically a good one, but it has it's own inaccuracies. It is in plentiful supply and is very cheap.
