Streamer just a nut fit in Thumb bass?

[lawjcrg]

Hello. I'm new here. I have an early Warwick 5 string thumb (I think it's built around 1988). A while back I had a bone nut put in to replace the original just a nut. I wanted to swap out the bone for the original brass just a nut and, unfortunately, the original brass nut is missing. I have the opportunity to buy a 5 string original brass adjustable nut that came off a 5 string streamer, but I don't know if this is the same size as the nut for the 5 string thumb. I can't seem to find any information about this online. Can anyone offer any help? Thanks in advance for any useful comments.
