TT artisan viewfinder for Mamiya press with 75mm lens

…I find the OEM bright line viewfinder rather poor with indistinct frames. Do you think I could use a TT art. vf designed for 35mm lens instead? I looks nice and is inexpensive. I’m really asking is the viewfinder for full-frame or apsc? I have a Voigtlander 21mm for the Press 50mm lens and it works well but this brand is too expensive in 35mm or 40mm field-of-view. Thanks if you can help.

I use a TTArtisan 28mm viewfinder for the 65mm lens on my Fuji GL690. The "28mm" on the TTArtisan indicates the focal length for 35mm/FullFrame. I assume one marked for "35mm" focal length to also be FF. Note--the 28mm doesn't have frame lines at all, I assume the one you're looking at to be the same?
