Have googled without success and wondered if anyone had any bright ideas.
We have standard window locks on (old) sash windows - you have a little key and they come off. And eventually get lost... So we need a few replacements.
Local hardware shop only sells the whole system (the bit you fit into the window, plus acorns and keys), and they cost £9.50 for 2. We only need the acorn bit, but I can't find anyone who sells them - any ideas??! Thanks
