I’ve seen brass eyelets that look like someone’s dehydrated piss and I refuse to chance it when I’m modifying a shell boot. The Viberg factory ones always look better than cobbler eyelets at least for me so I want the original.A cobbler should be able to source your brass eyelets in the sizes Viberg uses anyways. The soles are all branded, but I think the Viberg LH soles may actually be from the lactae hevae Vietnamese factory, one of the cordwainers in the GYW subreddit actually sourced the exact same ones from there. They have no proprietary soles come to think of it. I think a lot of people did go to Pekin and the like for customization as a direct result of Viberg being unwilling to do stuff like that by and large.
