Are you sure you have a 5x7 Press, or maybe you have a Commercial View. I have never seen a B&J 5x7 Press, but I have a 4x5 Press and a 5x7 Commercial view for sale. I might be tempted to sell the 4x5 reducing back from the CV separately. https://www.photrio.com/forum/threads/b-j-commercial-view-5x7-4x5.157236/
got one without pins to mount. You can use nails or some other for mounting pins--youre better off anyways--the pins sometimes don't line up from one camera to the next. f you're in the usa I'll do the deal--send me a private message with your offering....rubbing hands together...excellent!
