Your first picture is terrible. Try flattening the paper out on a flatbed scanner and do a JPEG image. I blew up the first image the best I could then added the second picture as a composite. The specs look the same ???? If that's true, then the hand drawn text for the lash amount is ???
Also note the hand drawn Duration of 254 and 264 on one page but the other page is cut off. Are you sure you have a Bulldog (Langdon)? It may be Patrick's or Delta Cams. If you think it is a Langdon cam, they are still in business. Contact them and let us know what you have.
Just curious. Is this paperwork that came with the car you purchased and are trying to identify which cam you have?
