2 X KVK2 for opinion

[Eryk]

Hi
I ask for an opinion on two KVK2.

First signed 9
According to me it is good - but I prefer to make sure.

And the second - without a signature.
You can determine who the manufacturer?

second one has a replaced ring IMO. Can't tell the maker ? The first has been cleaned & fooled with.

Hi
Thank you for your feedback Tom.
The first looks like it was cleaned.
