Can I please get some help IDing the makers marks on them?
The largest one of them that still has it’s sliding dust cover has written on it - REG TRADE MARK with a makers mark of a face and HANDMADE SECURE 8 LEVER. I got the dust cover on it and the other one that still has its one working.
The small brass lock has- CHADMOOR ENGLISH MADE, DOUBLE LOCKING ENGLISH LEVER and a owl face looking symbol.
Another one has that owl face symbol as well as a different makers mark and TUMBLING LOCK and there is another one the same as it that is missing the dust cover but I believe to the same type.
