I do remember the passphrases used.



As an example (I did this online because it's only for testing):
  • Go to bitaddress.org
  • Click Wallet Details
  • In privkey field, enter "longpassphrasetoremember"
  • Tick "BIP38 Encrypt"
  • Enter "extrapassphrase" and click Encrypt BIP38
  • Click OK to use it as brainwallet
  • The resulting encrypted privkey is 6PRKrgToVFyMzHL3qYa9Pq7e1ZugAiaYGYUxK2ccVaUoSeK9PYnqFti5Br
  • Now create a new brainwallet out of "6PRKrgToVFyMzHL3qYa9Pq7e1ZugAiaYGYUxK2ccVaUoSeK9PYnqFti5Br-1", and use compressed addy 14ut6qNTdRaexXRtMjYQc7bkStr2FLNfhk to store funds (don't use this one, obviously)
  • Before funding anything, see if you can reproduce your address from scratch
This is what I did. By now, a Segwit version would be better.
Maybe I am missing something, but if you remember the passphrases used? Why couldn't you just use the passphrasees to generate the private key and address?

I don't really see much value in knowing the details of the transaction if you don't know the private key, and the private key can lead you to information that will allow you to get the details of the transaction so you can create a new transaction to spend the coin.
