The Matchbox FT-17 is a good kit, accurate and easy to build, but it's only drawback is its scale: 1/76. But I recommend it, and will soon post a review of this oldie but goldie.
I was keeping one Matchbox kit as a real treasure, but I'm certainly going to get some Revell kits! Pity for the Char B1bis, which I'm definitely not going to build... I've got one Renault in Lithuanian colors, and have Estonian, Polish and White + Red Russians in the planning. This Renault model is great and much better to build than RPM's model. The Hotchkiss is well detailed and you can get hatches opened. There are also some usable figures included. Great move from Revell!
