4 1/2 NH Drag

Can someone give me the dimensions for the tight twist or slow twist drag. length and with including the diameter of rod used. I cant find an original so I'm going to make 1 for my personal display. Thank you in advance.

I doubt you will get much help with that . There are enough fakes out there that cause enough trap collectors to get ripped off that putting more out there isn’t something many collectors are excited about.
