When did we start calling profile cylinders "euro cylinders"

[1d4]

Unless I am mistaken, the two terms are used interchangeably, with the term "euro cylinder" being the more common one these days, at least online. But to me, a "euro cylinder" should refer to any cylinder that is made in Europe, not just profile cylinders. And what about profile cylinders not made in Europe? Would you still call them "euro cylinders" ?

The LIST Council does not have "euro cylinder" in their dictionary. But they have "profile cylinder":

profile cylinder
n. a cylinder with a usually uniform cross section, which slides into place and usually is held by a mounting screw. It is typically used in mortise locks of non-U.S. manufacture.

So, when did people start saying "euro cylinder" instead of "profile cylinder"?

Never, and if someone is doing it, then it's kinda lazy on their part. I think depending on when you started picking, which forum or youtube channel or locksport group meetings you were part of, and which country you are from, there will be some variations on what people call different lock parts, shapes, and lock pick profiles.

Most people I know call them Euro profile cylinders, Euro Din (DIN Standard 18251) cylinders or just profile cylinders, unless you want to get nitty gritty about Scandanavian or British Ovals, and other shapes like what they have in France and Portugal.

This may not answer your exact question but here is a post from 2003, scroll down to Euro Profile Cylinder viewtopic.php?t=1069#p6268

I've never actually heard anyone say or seen anyone type out "euro profile cylinder". The "euro" part seems unnecessary there, and makes it sound long-winded. But that makes sense. As long as we're all talking about the same thing. I just never got the memo.

I have used the term Euro profile cylinder and profile cylinder. Never used Euro cylinder. There are other profiles, such as the Scandinavian or Australian Oval cylinders, Swiss Round. But normally a profile cylinder refers to a overall format like that used by most locks made for that area.

More and more profile cylinders are showing up here in the United States. They are being used in a lot of 'security doors', and are usually horribly fitted. You would think that a company making doors all the same size and thickness would at least order locks that fit.

99% of the locks here in The Netherlands have this profile.
For me it's cylinder or lock. But the thing in a door that holds the lock is also a lock.
The pins are also cylinders and the core is also cylindrical. It gets confusing very quickly.

I often start with "Euro profile cylinder" and then continue about talking about the individual items with generalised terminology.
From oval cylinders there are a couple different form factors including: UK, Scandinavian but also Australian.
I'd state the model when if it's important for the function.

I attempted to find the change and found nothing interesting.
