Same Steven, though now having handled two marked small Bird & panel vases, I have come to the conclusion that differentiating between Sowerby & Jobling production of this pattern is not as easy as I first thought. It would appear that at least two distinct moulds were used by Jobling for this pattern, some have a prominent horizontal ribbed pattern to the tail feathers, while others have slightly more pronounced moulding with better defined feathers but with markedly less ribbing. My green marked example was of the former type, my pink marked example the latter. I also have an amber example of the latter which I am certain is Jobling despite being unmarked.
The ones I handled and were sure were Sowerby, i.e. in colours not consistent with Jobling's output, often but not always had prominent ribbing on the tail feathers and also stood a little shorter, generally 8 1/2 inches tall rather than 8 3/4 for the marked Jobling examples. They all had untidy mould seams at the foot with signs of repairs to the mould visible. As you youself say though, caution is required in drawing conclusions from a relatively small sample. My observations are based on the examples which have been through my hands which amount to about 15 by my reckoning, four of which I am confident were Jobling, the rest, probably Sowerby.
The difference in moulding can be seen here:

The amber vase I am confident is Jobling given that the colour & finish are consistent with my large 11500 Bird & Panel vase and the mould details seemingly matched my marked pink example).
I have since sold on many of these vases and have just kept my amber example and green marked vase, it is perhaps a shame that I did not keep them all so a more careful comparison could be made. I hope to get chance to photograph my marked green one over Easter.
