A buddy of mine gave me an older pair of, rather beat up, Fatshark goggles (pictured) that he got as part of a bundle purchase off Craigslist.  He was told they were Teleporter V4's.  I began searching for replacement parts (eye cups, shell, bay doors) and quickly noticed that what I have looks nothing like Teleporters.  The button configuration looks more closely like Dominator V2's minus the DVR controls (these do not have DVR). I've done a fair bit of searching and checked Fatshark's listing of old manuals to try to find a match with no luck.

Can anyone help me identify what these are, where I might find replacement parts, and if the Fatshark faceplate would be compatible with these?

Thanks in advance!

No, they're old Dominator V1

Yup, Dominator V1.
And if I recall correctly faceplates where not existing back then.
Might be an option to try a faceplate from someone, reason why:

I had the attitude googles back in the days and when the faceplates came out tried them out.
They did not click into place but you could still use them by just having the strap hold them pressed to your face.
Just a bit of hassle putting them on but all in all very doable.

Thanks guys! I was able to contact Fatshark support and they have one shell left in stock.

I appreciate the quick help.
