Hello team, I just noticed that ALL my Gougler model 200's, that is the round 18 notch clicker, have a # on the very bottom of the rear case. NONE of them have a # on the shackle..... well that is until now.. I just noticed while cleaning them & dedicating a case for them that there is one that has NO numbers on the back....other than pat pend.It has the numbers on the shackle like the model's 30 & 40 have.. I have the combination, so I am not searching for it, but I AM WONDERING if this could be a real early one as it is the only one that has a bare back & numbers on the shackle.. any help appreciated.................donnie...............
