A quick search of google with terms like 'd2jsp 08 gvalk' 'd2jsp ethereal 08 valk' etc suggests there isn't really any evidence trail of there EVER being any trusted 183 valks. D2jsp is well indexed in google and you can have an extensive review merely with good search terms in google.
Sure you might know some ingame goblin you met in 2012 told you theirs was perm, but everything I am seeing personally suggests they definitely don't exist. I'm not in the cool kidz circles so not 100% but looking very highly likely this doesn't exist and low key I've been getting triggered by your bumps
