I have recently purchased a Burke & James "Grover" model wooden camera, it is a 5x7 monorail, with a poorly functioning packard shutter and has a barrel mounted 190mm F4.6 wollensak raptor lens (that is scratched). I will be shooting portra its and landscapes and I am in search of the mystical LF clarity. I would like t o change the lens and shutter system into one that would give me more control in stead of the fixed f-stop and shutter speed I have now. Keep in mind that I paid less than a $100 for this system and I would like to keep the cost under $300 f or a used configuration. Any help or recommendations will gratefully accepted, t hanks.
