Munster Joinery window fixings (County Cork)

I am looking for tilt hinge and tilt hold fixings for older Munster Joinery windows (parts no longer stocked). If anyone is upgrading/retrofitting you might have these available . I will collect or send stamped address envelope. Need the hinge especially as cannot open window without this . If a few of each part available that would be best as spares would be useful. Windows were installed circa 2009. Thanks
