i have these rifles which i know nothing about

http://img684.imageshack.us/g/dscf3905.jpg/

the shorter one with the hex barrel at the breech end is 41 inches long with a 16 inch barrel and is smoothbore

the longer one is 42 inches long with a 17 inch barrel

i thought they might be " Roland's" but they are not the same as in hillier`s book , some similarity's as to a greener and i believe Roland's have been sold as greeners. what these are i have no idea
can anyone shed some light on them,
many thanks in advance
cheers
