Hi,
we acquired a TP Junior Reflex that comes (amongst others) with what looks like a Riteway roll holder. That's how we identified it from the pics, using a Butkus manual download. We're curious to find out if it will take 120 roll film, but also - hence the question here - if these holders are as rare as the scanty Google results makes them out to be, and if there are more out there owned and used and possibly praised by owners yet unheard of. It looks like it could be an interesting device.
TIA,
Norm
