Help releasing Black Bank multi-sig escrow

I'm trying to help out a vendor release funds tied up in a multisig transaction.

I found a guide on DeepDot Web (add /2014/02/16/blackbank-market-now-offering-multisig-escrow/ after the normal DeepDotWeb address) that details how to release funds. The guide mentions a "finalise early code", but what if this code is unavailable?

I have both private keys that brainwallet generated (what they call "Private Key (WIF)" and "Private Key (DER)")

I should have waited 5 minutes before I posted this..

Anyways, for future reference, doing research i found these posts: https://www.reddit.com/r/DarkNetMarkets/comments/379a02/bb_btc_in_escrow/ & https://www.reddit.com/r/DarkNetMarkets/comments/365olq/do_current_multisig_markets_offer_the/crklgh8?context=3 from user /u/hksupport

  1. The vendor needs to download Bitcoin Core and let it synchronize (takes a couple days)

  2. Vendor needs to enter the SignRawTransaction command into the console with both your private keys (BB provided it, looks something like this: signrawtransaction '0100000001dc00fd600c4871c09295b1c87d5c584e5e30f49d1b5954ddedd4f2ae851c94e80000000000ffffffff01a430b52a000000001976a914867fc69738d898f6a6ad915bdd8d451df3ceec5d88ac00000000' '[{"txid":"e8941c85aef2d4eddd54591b9df4305e4e585c7dc8b19592c071480c60fd00dc","vout":0,"scriptPubKey":"a914ee319ca638c466579bdb0e3d5540b14e0c54609187","redeemScript":"5221025ed410450dedc9468700ab152bb314673c2db72d8cc280872151959b79626e542102830a7d643718258413d1462030e187926429aa668f3abe919c15aef763687c422103905422830205b6736631fe4d0bbaf42a4209886a1ba08616ff6ed7db75aaa49053ae"}]' '["PRIVATE_KEY_A","PRIVATE_KEY_B"]'

  3. Then make a SendRawTransaction with the output. I saved a screenshot of BB's guide that explains everything here: https://infotomb.com/jb9tz.png

  4. Congratulations, the vendor now has his coins. All of the above should only take a couple minutes.
