Here is the little devil wanting a drink of a fine penetrating oil. It is definitely "stuck" as it should protrude from the front of the frame, not be flush, when the action is open. This particular VH was completely seized with rust and "crud". All metal was soaked for a long time to begin to free up the parts. The screw that holds this group in place has a small head. I used jeweller's screwdrivers to finally remove it to clean off all contaminants, as well as the bore through which it moves.
Cheers,
Jack
