Saw these on ebay and it really took me back to the 1970s when Lynx hit the scene. I remember a lot of good amateurs buying some and saying they were great. When Lynx went cavity backed they never seemed to have the same stylishness. I'm not attracted by this asking price, but would like your opinion of their place in the vintage scene today.

Lynx clubs were very expensive when they came out but had a good following.
These are more cavity back than blade, they also have a big offset which personally I don't like.
I don't know what date they are but I'm sure you could find out with a bit of searching.
