Just bought a Horseman LX from Peter Walnes on ebay in exc++ condition for £251 delivered with a 14 day approval period (ebay item 370611489247). I have dealt with Peter many times before so have no worries as regards the expected condition. I have done a search but cannot find a manual available anywhere for it.

So I have a few questions:

Does anyone know where I might find a manual?
Is the back a standard Graflok back or a design specific to Horseman?
Are then any accessories that are a 'must have' for the Horseman LX?

Any advice gratefully accepted.

TIA.
