I've searched old threads and found there is a small hard-core group that shares my enthusiasm for this camera. I'd like to hear about any modifications any of you have done. This camera is a tinkerer's delight. Here's what I have done over 20+ years: *Had a custom Polaroid back made that focus at the same plane as the film backs. It uses the bayonet mount for the revolving back. (the talented machinist who did this passed away years ago, please don't ask how to get in touch with him.) *Made a 4X5 adapter for my 6X12 back that also focuses on the normal film plane, thus allowing standard hand-holdable rangefinder focus. It uses the rectangular belows and ground glass back from the obscure Horseman HF 4X5 body, with a little digging and grinding in the VHR body. *Modified the viewfinder with 6X12 frames using silver slide mounting tape. *Installed two bubble levels (one for pitch and one for yaw) in the VHR viewfinder that can be seen via mirrors at the same plane as the frame line. *Use a 65mm with full rise and a 45mm with partial rise, thanks to third party recessed lens boards made by Scott Bonnett several years ago. (Contact Bob Eskridge, he may still have some for sale.) Why hasn't Horseman continued developement and made these improvements themselves?
