Well numb nuts, there is no such mower,...the sprint is the model of the Briggs & Stratton engine on your sovereign doh !!!"!! look at the rear between the engine & handle mounts, & there will be a silver sticker plate with the REAL model number...numpty !

There are shops that specialise in Garden Machinery - check out yellow pages - try to remember where you bought the mower.
XP 40 very probably means a 40 cm blade.

what type of blade do I need for a sovereign sprint?
