is a good idea but a not have idea of my version of Cessna 150 I found in a barn and i i make restoration. There is only plate near engine mount with only serian number.
have landing gear Round section, and i presume is REIMS factory
There should be a serial number on it somewhere, Fabio, that is the best reference. If it is a Reims, it will be look like F150xxxxx or FA150xxxx. Here in the U.S. we have a data plate near the tail with the s/n on it.

Here's some photos of the tanks, fork, and flap. The flap has some slight bending on the edge, but it looks like it should be an easy repair. The dark streak on the fork is a reflection. The metal is bright and clean with no scratches or pits.
