New Zealand Mortise door handle

hi was wondering if you can match this mortise door handle it has made in new Zealand on it
the small lever with enables you to lock it form the inside is broken and it has locking barrels on both sides
This however is not a must but it would be handy to make it a dead lock fron the inside

the screw centers are @ 125 mm apart
slightly under 5in
Any assistance you could give would be greatly appreciated
i look forward to your reply
cheers
Peter
