Help me identify these sculling oars please...

[fatgrosshog]

Someone told me that the sculling oars in these pictures are very expensive/rare/valuable/high quality, but anyone can say that so I'm wondering whether someone out there can help me identify them. They don't have any writing or logos on them and I've looked online and I see oars that look sort of like them from several companies. I don't know how old they are or where they came from other than that this guy had them in his garage for a long time. Can anyone help?

Here's a link to some pictures of them (I didn't know how to attach pictures to messages in this forum, sorry):
