Funny follow up on the 1263! I found another one in my collection, but something about it was not right for sure. This one is an FEH so has the green hardware. First red flag is it only has 3 guides and tip top, second is that the two sections are different length and rod measures 68", when put together 5'8". Also handle appears to be 2" short and the tip top does not look original and has no winding below it.
Final theory is that the rod was cut down or broken in 2 places and was originally a 6'6" 1263. As shown in the photo below, if we add the 2" back to the butt of the handle and the 8" that appear to be missing from the tip to the bottom of 1st guide and using the guide spacing from the 6' model we get 2 sections at 40" which when put together make a 6'6" rod!
Mystery solved...Maybe! Could maybe redo the guides and have a 5'8" 1263 custom!
