Are these Herse cantilever brake arms?

I've asked about this on the Classic Rendezvous site, but nobody has acknowledged knowing of Herse brakes with these forked ends on the arms. There seems to be a prevalence of opinion that these are Herse, but I'm still a bit skeptical. Maybe they are Toei copies? Anybody familiar with these brakes?

The story: I recently bought the contents of a shed that belonged to a racing and touring friend from the early '70s. He worked in a bike shop (Zumwalt's in San Diego), and acquired a lot of odd stuff over the years. The shed had not been touched in 40 years, so nothing in it is recent.

I found these brake arms in an old Cibie generator light box. They appear to be unused, and they appear to be Herse cantilevers. However, I haven't found any evidence that his brakes ever used a forked end like these do. The forked end is apparently intended to receive a binder bolt on the straddle cable as Mafac brakes do.

Thanks!

Re:

Yes, they do look like Jan Heine's reproductions. But, they have been in a shed for 40 years and the reproductions have only been available for a year or so. For mine to be reproductions, we would have to go all wibbley-wobbley timey-wimey. Also note that only one side of my arms is forked, and the other side is the commonly seen original Herse style. Thanks!

I knew you'd say that.

I was reading about a Japanese randonneur a couple of nights ago and it was completely Japanese built and it had herse copy brakes on it made by Toei. I will see if I can find the photo.
