The Fujimi kits aren't bad; they'd probably be considered really good if the Italeri kits weren't available for comparison. But the Italeri ones are much, much better detailed and more accurate. Take a look, for instance, at the small boats, or the details on the fantail bulkheads.
I'm not familiar with a Revell pocket battleship kit. Some Revell Germany kits are reboxes of Matchbox and Italeri ones. I can't recall seeing any warships in that category, but if Revell is selling the old Matchbox
Graf Spee - don't bother.
One nifty thing about the Italeri kits is that the company made a genuine effort to depict the differences between the ships. Some of the differences are pretty obvious; the superstructures of the
Graf Spee and
Lutzow are so distinctive that they don't look like sister ships. But even the changes in the searchlight platforms of the
Graf Spee and
Scheer show up in the kits.
As a matter of fact, if I'm not mistaken Italeri did four kits:
Graf Spee, Scheer, Deutschland, and
Lutzow. The latter two, of course, are two names for the same ship; the kits represent her at two points in her career.
I'm sure there are some inaccuracies in these kits, but they represent a level of concern for accuracy that's rare in the industry. In my opinion they're among the very best mass-produced plastic warship kits.
The Italeri H.M.S.
Hood is also a beauty. In some respects it's better detailed than the Tamiya one.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
