Internal thread specifications 1

I need specifications for an internal thread that is not common, it is a 3.875-32 thread. Does anyone have reference to this thread (i.e. pitch dia, minor dia, etc...) or a source for this? I can't find this thread anywhere. Thanks in advance...

 

go to your machinery's handbook and use existing formulae for determining whatever dimensions you need.
