Looks like another Henry James crown, but with the "K" logos in the top(s). Are they cast or milled (deeper cutting than I would call "pantographed" but maybe that term still applies)?

This is the fork crown we use on the transportation bicycles we build in Ukraine. All parts of it except the blades were made at a laser cutting factory south of Kyiv. Since they have the capacity to cut things out we thought it might be a good idea to braze on a cross on top of the crown. One out of 100 thieves (or maybe 1000) just might decide not to steal it when they see it. Anyway I think the cross looks cool.

A twin plate crown is complicated to braze accurately so the plates aren't twisted and 90º to the steerer and exactly the right distance apart. We had to design and make a special tool to hold everything in place. Nolan - one of my students - helped me design it. He turned to making frames as therapy for his cancer. Sadly he didn't make it even though he was only in his 30's. He was one of those that had made plans to spend a few months in Ukraine brazing transportation frames to sharpen his skills.

The picture of the fork jig is just outside of the frame shop in Ukraine. It is just past the tops of those trees on the horizon I saw that biggest cargo plane land one time. I'm sure that peaceful scene is no more since that is exactly where the head of the Russian convoy is now stalled.

Here is a beautiful fork crown Tom Kellogg prepped and Ronald Della Santa brazed. It is part of a project 10 American builders - that started in the 70's - did as a collaborative effort. The lug you see was done by Brian Baylis. He not only shaped it but also added brass to the transitions to smooth out the radius between the joints. I added the braze-ons and did the painting. 3 of us have already passes away. Bruce Gordon did the dropout treatments.

The pictures were taken in 2018. Covid and the invasion and a lack of bicycle parts supply has prevented me from going over since then.

My 2007 Vanilla, the last shot is after I went with a bigger tire which required a larger fender and a "daruma" bolt to hold it instead of the elegant "floating" mount Sacha used initially.

The difference I've seen with the Taiwan knock-offs is that the Taiwan crowns have a pocket into which a slab of brazing material can be inserted:

Thanks for the request, pic below hopefully helps. Not 'road' gears, but all possible in the '70s thanks to SunTour and I need all the mechanical advantage I can get. I don't think the paint is bubbling (note to check) but the close-up has revealed the need for a bit of a wipe! The black deposit is brake pad dust, together with mud and grease from the crown race. There are one or two flies as well as the first sunny/warm weather of spring has brought them out.
