I believe most are Ysart Brothers / "Salvador Ysart 1930s".
Canes 2 C and 4 D (one of the butterfly canes) are included in the well-published images of a selection of "Salvador canes" - see, for example, inside covers of Bob Hall's Scottish Paperweights book.]
Note that the two Butterfly canes are different. The one at 1 C is an example that I had only seen in some Paul Ysart weights, until a few weights turned up with that cane and which were clearly Salvador Ysart / Ysart Brothers.
It was the use of the 4 D cane in both Paul's work and Ysart Brothers & later Vasart (etc.) that gave the first clear evidence of "1930s cane sharing" at the time when Paul stayed at Moncrieff's and his brothers and father formed Ysart Brothers Glass. The 1 C cane has now been confirmed as also being a "shared cane".
[Above two paragraphs edited to get my info straight!]
Three that I cannot determine are: 3 C, 4 C & 6 C (need close-up details of each)
Ones that are possibly Ysart Brothers / "Salvador Ysart 1930s", but which I do not recall seeing before are: 5 A, 3 D, 1 E and 7 E (close-up views would be useful as the internal elements may prove what they are)
