Hi
This is my first post, I am an engineer by trade not a locksmith so forgive me if I don't use the correct terms. I recently purchased the lock below and renovated it, purely for display use. The only information I could find was in The Gazetteer of Lock and Key Makers, see below.

"The company adopted a novel trademark. While on holiday in the Isle of Man Mr Legge found himself studying the famous symbol of three legs. Struck by the design he was determined to adopt it as a trade mark; but it was not without the greatest difficulty that he secured permission.
The sign of the three legs is still used today and, in the post war period, was a symbol of his three sons actively engaged in the business."

I assumed my lock was a Victorian Eastlake but am I to assume this was made after 1945?
I would be grateful for any help to clarify this.
