Does anyone know what this gutter bracket is?

[Tobyge]

I have several brackets for gutter hooks mounted under the roof sheet on the barn that lacks a drainage system. To avoid lifting the sheet to install new ones or to remove the brackets, I was considering if I could find the same kind when I set up gutters. I don't know how old the brackets are, but I would guess that the roof was replaced sometime between the 1970s and 1990s.

But here's the question, does anyone know what kind of gutter hooks these are and if they can be purchased?

Even if you find the right one, it seems to be too far apart between these. Mount new ones on the footboard instead.

Even if you find the right ones, it looks like the distance between them might be too long. Instead, mount new ones on the footboard.

Yes, the distance is about 1 meter between the fastenings, so it's probably a bit too long. However, the barn is quite long, so if I were to replace all the hooks with cc 60cm, I would need about 200 hooks But it seems like that's what I'll have to do, but I was curious if anyone recognized the fastenings for the old hooks!?
