Sorry I'm a year and four months late on this reply.
That was a NOS Coloral bag support still sealed in the original plastic bag with cardboard peg hanger until I got hold of it...
I held it for a year before I decided to use it on the Lenton
Nice build and details, the result of your efforts is outstanding! Really enjoyed the build, thanks for sharing.

These were not difficult to find on ebay when I bought it - I know I had a dozen to choose between, and a couple of brands/styles.
Today, the only one I could find was rusted and over-priced.
If I had known what the market was going to do in just 5 years, I would have bought them all.
The second most common style is given credit to Brooks, but the common brand name began with "M" - middle-something- I wish I could remember it.
Maybe
@juvela can help.
