I found a cam that a friend of mine has and the numbers on the cam and initials are GTP/420-112/ 1201103 and a number under this one is 2871. If anyone has any idea let me know something or if you can just let me know what the GTP stands for that would help out a whole lot. If there are any questions just leave them here and I will get back with you as soon as I can, until then thanks, later.
