Thanks for the reply Dean.
I was curious and I thought you were going to say something like the finish on the ???? was a deeper tint or something very forensic and technical.
You have also explained what a ‘fantasy’ lock is, thanks for that. It’s obvious when you know!
The difficulty with this site is we have some real experts and some enthusiasts. I’m in the latter category, work with modern locks so I have a certain knowledge but not specialised. My collection was mostly obtained by accident and ‘free’ so I haven’t had to study to avoid the pitfalls of buying the wrong stuff.
I own a few of the late Peter Philips’ keys and his trick casket of which I’m proud - couldn’t afford much else. No padlocks.
Thanks again
Richard
