(I think I missed to point of the original post in my earlier
answering post above.)
I found an 828 film size negative carier works well for 35mm with
border showing. Beselar has them, maybe others too?
You may want to avoid using tape with B&W silver prints, or you may
soon see color changes near the tape (unless the tape is specifically
made for silver prints).
Hope this helps.
