Hasegawa 1/72 F11F-1 Tiger (short nose)
Here's my Hasegawa 1/72 F11F-1 Tiger with the short nose. The nose is a resin replacement in the kit. All you have to do is cut off the longer nose from the fuselage parts and plug the resin replacement in. Mine fit with just a bit of filler, but I think that was more due to my poor job sawing the original nose off! The short-nose version also does not have the leading edge extensions on the wings, so these need to be cut off as well, which is a simple task.
The last picture shows the short nose and long nose versions side-by-side so you can see the differences. Both kits are fast, easy builds. The long nose version can usually be picked up at your favorite online auction site, but the short-nose version is hard to find.
