What I suggested is likely, it's not possible to be sure from this distance.

Don't worry, I won't hold you to it!

Most bike shops have some sort of seat post gauge, either electronic calipers or a very slightly sloping tube with markings to indicate the correct size.

Go to a local framebuilder,proper bike shop, they will have for certain a reamer.
Get the job done properly; no problem!
