Just saw this and checked the arsenal stamp database. I do not see it on there. Looks like either an 0606 or 6006 to me. Thoughts?

Thanks GG. Looks like /636\ to me...

Thanks GG. Looks like /636\ to me...

Most definitely a /636\. Most common arsenal after /26\ and /416\.

LOL, I tell ya my eyes are going. I couldn't get it zoomed in enough to clearly make it out. Sure looked like 2 zeros to me.

That is the third most common arsenal? 
Well, their machining looks to be less than desired. 
That and the fact I don't have a /416\ either...nor have I seen either...
I feel almost elitist with the arsenals I have.

What REALLY bums me out is the fact that, now that you guys have pointed out it being a 636, it is quite obvious to me. Having said that, Justin, I have not seen either of those either.
