This is an unused Cervellati pad, I had this fitted to my Crown 20b, but then sold it to buy a Perazzi.
The pad was therefore taken off and the original Pachmayer refitted.
The Cervellati Microcell pads are the lightest pad made - this one weighs 1.65oz, the standard Pachmayer pad weighs 4oz and is a lot heavier and sticks in the shoulder.
Many sportsmen fit these pads as they are a lot lighter and shift the balance slightly forward which is far more shootable than a butt heavy stock.
Dimensions are :- 44.2mm wide x 135 mm long x 15mm thick.
Screw holes are at 80mm apart.
It is ready to fit straight to a Browning Crown 20b instead of the sticky and heavy Pachmayer Pad.
When fitting lube the screws with Vaseline, grease or washing up liquid to avoid damaging the microcell rubber.
