I have a match 54 for sale at Crewe R&P club for £325. The serial number has the much sought after "X" suffix.
The stock has the standard adjustable height cheek piece. Price includes front and rear sights, hand stop and bipod.
I know that it is accurate because it won the 2015 Div 2 Staffordshire 50 meters Benchrest competition despite the limitations of the owner.
Hope this helps.
