It's a style of field camera made by many companies, in fact you could buy the components from Lonsdsale Brothers in London. Often identification can be easy, based on the type of front standard fittings, how it folds, often Patented. Holmes Bros, later 1904 part of Houghtons, made and sold Sanderson cameras, that was not the make of camera instead it's acknowledging the camera uses Sanderson's Patent style front standard.
One of the few types of front standard fit not Patented, or maybe lapsed, is the two rod down either side of the front standard locking it to the focus bed
Here's the same system on my Unknown 12"x10" field camera. Another factor is often cameras even from large manufacturers were sold unbranded and a wholesaler or retailer would add theirown name badge.
