The updated Barling Pipedia page is just fantastic!
Great stuff!
This odd pipe sold just yesterday for around $100, pretty interesting...
I do not own a Barling as of yet, but hopefully one day I will.
...here's an oddball with another strange stamp, this one says Benjamin,
I love this Japanese site!

Another Japanese site has a really nice Quaint, a similar square panel to the recently sold pipe...

Another period term here, "pre-Nichols"

Prior to the "Nichols-era", Barlings had minimal stampings, with the only real designation of a higher quality piece being the "Ye Olde Wood" stamp. In addition, Barlings rarely had shape numbers, although size stampings seem to be something that came about in the 1930s.
...and I find these WW1 era soldier carved Barling's to be interesting:

Barling has such a rich intricate history, I think perhaps amongst all the famous old British marques, that Barling's Make is held in the highest esteem of most collectors.
