The M41 Walker Bulldog was a light tank used by the US Army in Korea and by the Army of the Republic of Vietnam in the Vietnam War. They were designed to replace the M-24 Chaffee, which due to their size they did not manage to do successfully, and with its 76mm gun not being very powerful, it had a short service life.
I think this model kit is great, you can get them cheap, and they would be a good experimentation kit to use for green vehicles, costing in Germany around 15 Euro, and you end up with a good product at the end of the build. I think for its age and simplicity, it is a really good kit, and I think these simple kits are the ones that are the most fun to build. Another one that is also so inexpensive is the Panzer II Ausf F/G from Tamiya, also simple to build, and looks good when its finished, I built two of them already, As for this kit, without Aftermarket it builds into a good model, but there are also a lot of AM parts for it so you can really deck it out. Here is a link to the available parts (availability not guaranteed though)
