Ferrule sizing

[ctroy36]

I need some help figuring out what ferrule size I need. I'm trying to refinish my old Montague bamboo rod, which is a two-piece, two tip rod. Unfortunately over the years I've lost all the old ferrules except the male on one of the tip sections. The OD of this one is 13/64ths where it goes into the female. All the ferrule sets I've found on the Internet are listed by IDs and none lists a female with a 13/64ths ID.

Any suggestions?
