Hi Benottomadmax,
Nothing seems to have posted but I have a Benotto 5000. Most tubes have been ovalised and the gear cables are internally routed. The rear wheel forks are diamond shaped. It has 'BENOTTO' cast into the seat stay caps and the fork crown (on either side). Two 'B's are cast into the brake bridge as well. The seat tube has been crimped to allow the rear wheel to tuck in closer to the tube. The bottom bracket has a 'B' cutout with an arrow shape cutout next to the 'B' cutout.
Here is a couple of photo's to help you compare frames:
