Looking for some input with my new buggy. Where would i look for any badges or plates for model/manufacture stuff. there is a fairly heavy coat of rock guard inside it.  the underside picture has what appears to be a cardboard or plastic tube fiberglassed  into the body 

Looks like a real Manx to me, especially with the battery box and the wire tube guides under the body. If it is, there should be a tag above the tunnel on the firewall at the front, inside the body. If you contact the Manx club and take a lot of really good close-up photos, they can verify the car.
