I started testing the recover wallet link you sent to see if it would be able to recover the wallet id. I did check 10 times to make sure the certificate of the website looked valid etc..and only typed the first two or three words. The first two words were recognised..but the third word was not. I tested with other words from the version 2 version of the dictionary and they also worked. It seems the link only supports version 2 words and not version 3, or there is some way to indicate to it that is a versions mnemonic that I am unaware of.
Or maybe there is another URL for version3 recovery.
 I will keep looking though.

We have gotten access to his Gmail email address.somce he wrote down the password. But that wasn't the one used for his blockchain account. So now we are trying to get access to an iCloud email. But will have to reset that password. I must say apple password reset is a monster.

All the words match perfectly! Thanks for the suggestion, I would not have found this on my own. The fact that it is on wayback machine... makes it especially hard. So thanks for the suggestion! Wow, it's a wordlist of 65591 words that is very intimidating. The one word I couldnt check of course is the one illegible word (or I should really say missing word).
Thanks this at least seems to be the right direction! I will have to find out if my aunt still has access to his email addresses. But it might not even matter, since the one missing word could matter if we need to reset the account.

Thanks for the help everyone. I've tried looking up the words on the BIP39 word list and only 8 out of the 32 words match the words on the word list.

However, there are definitely clues that he didn't add the words just on the paper since he wrote it in the form:

In order:
1. word
2. word2
...
20. word21 word20
21. word21
...
32. word32

So at least that signals to me that these words were included ... However, the fact that so few of the words are in the words list is worrying. I can see a common theme in many of the other words though. They often seem to be biblical words like Heaven (made up example) or money related like (Fraudulent). Although I might just be seeing fake patterns here.

I'm guessing it's a lost cause overall though because it probably meant he used a huge word list right? If BIP39 has 2048. That means the added words were probably 8000 words. I know he didn't do this alone though, since he definitely wasn't tech savvy enough so, there must be somebody that created this for him. Or otherwise the electrum wallet - with the extended worlist might be on his old computer.
 

Hi there. I inherited a Bitcoin wallet seed phrase from my uncle, but he didn't capture all the details. It's a list of 32 words. However all the wallets I tried so far only use 12,18 and 24 words. The words also seem a bit different to the typical words I remember seeing in my own wallet phrases. Lastly the one word is hard to make out, but will cross that bridge once I know what type of wallet this is. Any help would be appreciated. Let me know if you need more detail.
