I have a 1.5”/ foot taper reamer for ball joints and similar. It is 7/16” on small end, and 1” on large.
That works out to 7.125* Not sure if your 7* spec is rounded from an inches per foot taper, the more common description for these things.

I don’t mind loaning it locally if it returns in a timely fashion and undamaged.
