Binder Pocket Sheets for unusual vintage sizes

I remember this topic coming up last year but could not find the thread, was hoping to find some good quality binder pocket sheets for everything from T206 - 1950 Bowman size cards.
Is there a specialty company that makes these to fit?
I look forward to the replys.
Thank you.

After researching everything I could, even business card sleeve sheets! I still cannot find sheets that can somewhat closely encase a '51 or '52 Bowman baseball card.
Please advise if you have information.
