I was prompted by Chris' posting on Lutken vase (
http://www.glassmessages.com/index.php/topic,37814.0.html) to post this one, but am posting it separately to avoid hijacking his thread
The attached pictures show a vase approx 7cm high, and 8.5 cm diam. glass is 2 cm thick (weight 750 grammes).
As you can see from the pics, there are incised lines half way up the outside.
The lines have been made in two "bands", each of approx 2.5 cm high, and overlapping.
Now the easy bit - it's signed Orrefors DH (or DU / PH / PU / PA) 3616
Swedish glass factories doesn't show this piece, but there is a piece marked FA 2179 (10 cm dia) with v similar patterning (named Kantarell)
It's also similar to the piece Chris refers to on
http://www.hardernet.dk/ "the 70th entry in the Lütken, Per kunstglas solo section" (search on 628), which in turn is quoting the item 250 in the unica section of Per Lutken's book "Glass is life".
The obvious answer is that it's Orrefors (the signature looks genuine when compared to other bits I've had), but before I jump to that conclusion I'd be grateful for others' thoughts.
