thanks all for the inputs.
I guess being new really makes things a bit difficult in doing the search, as I made various searches under different key words.

Anyway, keithwms, I took your idea and using my existing Paterson 3 Reel Tank I think I manage to come up with a holder.

As I don't really own any LF equipment yet (pardon me, I'm still doing a whole load of R&D before deciding) may I know if

the film thickness for a LF negative say is roughly the same as those of medium format?

If it is, then I guess the above may work, and development shd be pretty ok on both sides on the film using the Reel
