Rolleiflex Finder Adapter

Hey everyone,

New to the forum, so hope this is ok to post here.

I've been looking for adapters to use Hasselblad viewfinders on my Rollei 2.8F. I've recently picked up one on eBay, but I wasn't satisfied with the fit. Recently, I came across the Baier adapter, which looks great, but isn't available anymore.

Would anyone have leads on another option? Or perhaps know where to find a Baier one. Ultimately, I want to use a 45 degree prism, but none are really available for the Rollei. DHW Fototechnik used to make one, but they are painfully expensive on the use market (if you can find one).

Thanks!

Recently it was for sale in the Classified subforum.

Thanks Alex, I'll try to find the post on it there.
