I sent the vendor an email suggesting the attribution was misleading - "in the manner of" perhaps would be more appropriate.
I bought 4 vasart-style inkwells from the same vendor at the newark fairs on seperate occassions. I think the prices varied from £65 to £85.00 so the prices weren't excessive. I wouldn't have recognised an ysart fish from a mackerel at the time. However, there was a certain quality in terms of manufacture/composition. I've only a single example left now. My example has a profusion of identifiable strathearn and vasart canes, and although a single colour (the same green) has very distinctive spiral/stripes. Very similar to the example illustrated on page 166 of Bob Halls book.
