Yes, definitely a fire polished base on yours, M.
Yes, I agree with an attribution of: Strathearn but maybe late Vasart Ltd.
Regarding the canes:
1.
... the yellow middles in the beige canes are whorls open ended as opposed to tubes.
Really!! I have never seen a whorl cane used in any Vasart (Ysart Brothers), Vasart Ltd. or Strathearn weight. Can you get a macro image of one or two of those canes (maybe even taking a photo through a hand-held magnifyer would help)?
2. Whenever I see the use of many of those canes that look like "snowflakes", or "stars/cogs with castelated points" (i.e. three points to each of the main points) my mind automatically locks in to "probably a Vasart Ltd. or Strathearn" weight. In fact at one point I used to believe, with no proper reason, that it indicated a Strathearn cane. Then I began to see that cane design in Vasart Ltd. weights. And then I noted a few in some Ysart Brothers (Vasart) weights! So, just like looking at base finishes etc., specific cane features can also be a bit of a problem when taken on their own.
Also, as an aside, please note that weight No. 15 in my article linked to above should be noted as being a PP1 from Perthshire Paperweights. I should have changed the attribution some time ago!
