Derailleur Hanger for Guru Sidero

Derailleur Hanger for Guru Sidero
I have a 10 year old Guru Sidero that I absolutely LOVE and just broke the hanger. I am trying to track down a replacement (I believe the Guru Praemio used the same hanger), but they used a very unusual one (see attached photo). Also trying to be creative and think whether there might be abandoned Guru's or cracked frames or some other way to source this piece from a discarded bike. Just desperate to not hang up this bike for good due to a $25 part

Have you tried www.derailleurhanger.com yet?

yes, none of the online sites have it unfortunately, because Guru went bankrupt a couple years back. Have reached out to the company that bought the assets, but they have been unresponsive
I can't post a picture here in the forum 9Because I haven't done 10 posts yet, which is just stupid), but happy to send a picture if helpful

Apparently, you CAN post photos to you profile/gallery or something similar to that.

Once you get those 10 posts which is really easy and fun you can post the pictures (because if you just have one it isn't as helpful as having both sides of the hanger) and it should be findable.

See if these guys have a CAD file. Or get the old one welded up.

Similar problem
Yea, this is like very late, but i recently snapped the hanger on my old Guru bike also. I got a kinda old model, actually i'm not sure exactly what the model is and couldn't find any numbers stamped on the frame. I'm outside in Japan now and trying to find the part online, anyone got ideas where to start?
