Hi guys, couple of very simple (hopefully) questions

1. Is there a third party/cheapish viewfinder option for the Toyo 45CF (will modified polaroid MP4 work?)
2. The cambo monocular finder can be attached to super graphic via removal of the super back and attaching a cambo groundglass back, I'm just wondering if the configuration of the Toyo 45CF back would be similar and allow the same option?


thanks
