Ross Half Plate Field Camera HELP!

[Kierra]

Hey all,

I need a hand. For Christmas I was given this beautiful 1888 Ross London half plate field camera but the interwebs aren't being very useful in terms of finding out much about it. It came with a barrel lens and 2 what I assume are film backs. I cannot seem to find any info on how to load the backs, what the take ie. film or wet plate, or the best way to possibly try and use this with the barrel lens.

Thanks in advance.
