OK so I bought a used P2 4x5 it's in good overall condition and everything works as it should.
There's one minor thing I want to rectify, but I'm not sure if I'm being a bit precious so would appreciate some advice.
Basically the front standard sits slightly rotated (only a very small amount) around the rail in relation to the rear - it's fine until I tighten the standard clamp on the bearer, then it keels over ever so slightly, not a huge amount but enought to throw the level off between the rear and front.
Any thoughts on how to rectify this? The plastic 'runners' within the clamp look only slightly worn (but evenly on both upper ones), There are what looks to be some set screws underneath the clamp but I'm reluctant to fiddle without knowing if they have any relevance.
