My son has an Ariel Three. It was bought without a V5 (the owner had lost it) but a quick check of the DVLA system shows the reg. is still current. He has rebuilt it to MOT stage, and needs to get hold of the V5 to change the keeper to himself. The V5 needs a frame number input, and try as we might, we cannot find the stamping. He has a manual, and it gives a vague location (at the rear near the trunnion), but we simply can't find it. My worry is that it is either filled with paint, or it has disappeared during the rubbing down / prep stage!
If there's a Three owner on here, could you please tell me exactly where the number stamping is located? A photo, with number obscured, would be very helpful if possible. This should enable some targeted removal of paint, rather than the scattergun approach which is looming
And why oh why did BSA choose to stamp the number in such a dirty, dark, difficult place?
