The film's description lists three things Winkler made himself: boards, axles and wheels.
The LEGO press belongs to the first of those. It is the image Daniels chose to lead with, and it sits in a chapter titled "The secret laboratory". The description does not say what the press produced: how many plies, which veneer, what width or concave. Nor does it say when Winkler built it. Those are questions for the full film and for the archive pages behind it.
The wheels are the part of the work that became a brand. A chapter called "Winkler Wheels, pins and the book" covers that side of his output. The magazine has not confirmed from a first-party source what the wheels were made of, or whether they ran bearings. A buyer looking at one of those unopened boxes should ask the seller rather than assume.
Two other products carry his name, and in both cases someone else made them:
- The Winkler Mini. The description says Winkler got Blackriver's first signature ramp, and the film gives "The Winkler Mini" its own chapter. The listing Daniels cites is for a "Winkler Mini Dos". The supplied material doesn't establish how the two relate, or when either was released.
- A Berlinwood pro model. Berlinwood presses 5-ply maple decks by hand in 29, 32, 33.3 and 36 mm widths, and it makes pro models for riders. These are documented through Berlinwood's page on the Blackriver shop. The "Martin Winkler pro model" in the description fits that pattern. Its year, width and shape are not stated, and that pro model does not appear on the current shop page.
The film also covers Winkler as a rider, in chapters titled "He could ride, too" and "What good style looked like". It covers him as a personality in "The entertainer" and "The evangelist". The description doesn't summarize those chapters, and this piece won't guess at them.
