sorry about that.  one of my first replies suggested I post on the electrum board.
Yeah, that was me, but I didn't say create multiple threads in all those boards. However, there is no malicious intent in you creating those. But you should lock this one nevertheless. Scroll down to the bottom and click on the 'Lock Topic' button. It's best to keep all the info in one place.

Please don't create multiple threads on the same thing.

I have the following:
(these are just random numbers formatted to look real, they are not valid)

  • # User seed:  (53 characters)
  • # User public key: xpub661MyMwAqRbcH1atMf3cfeVgjA4SPncUpKx24PXcD3sY8dpkXapCD4EgviZ6EkEww9seSd7rum2 jRYz5rudFj6gHZT432sHSNHhysqFuYuC
  • # Shared seed (encrypted): (58 characters)
  • # Shared public key: xpub661MyMwAqRbcH1atMf3cfeVgjA4SPncUpKx24PXcD3sY8dpkXapCD4EgviZ6EkEww9seSd7rum2 jRYz5rudFj6gHZT432sHSNHhysqFuYuC
  • # Coinbase public key: xpub661MyMwAqRbcH1atMf3cfeVgjA4SPncUpKx24PXcD3sY8dpkXapCD4EgviZ6EkEww9seSd7rum2 jRYz5rudFj6gHZT432sHSNHhysqFuYuC

can I recover a Coinbase multisig wallet (created in 2016) into electrum using the steps mentioned in this post

The lack of a seed phrase is what makes recovering a coinbase multisig vault as difficult as it is.  
I am no python coder (not coder at all) but was able to get the code from this post on stack exchange https://bitcoin.stackexchange.com/questions/57207/how-to-derive-the-private-key-associated-with-a-coinbase-multi-sig-vault-address to produce something similar to the following:
(these are just random numbers formatted to look real, they are not valid)

  • Master Private Key corresponding to seed: xprvz3PCl3Goz8yXxYt9mx6I9B2YXNX7ulTU0O2a6T43OfjP23A2ahmwx72iJVkmTWy0ZmBZMZcIkVv bZteiiHkucAZFdK1m1kjfMB6542qggKO
  • Master Public Key corresponding to seed: xpub661MyMwAqRbcEzdGMFKZXuVwbyHY2zKhiw6YFTrULfNBF53QVfXyoAiKMZKWkQA5444NXtLj9HP mgyN1xLCiJJ9dKAy4nLZJ87trHRnwUDb
  • Extended Private key at index 14: xprvz3PCl3Goz8yXxYt9mx6I9B2YXNX7ulTU0O2a6T43OfjP23A2ahmwx72iJVkmTWy0ZmBZMZcIkVv bZteiiHkucAZFdK1m1kjfMB6542qggKO
  • WIF format of that key: 3OfjP23A2ahmwx72iJVkmTWy0ZmBZMZcIkVvbZteiiHkucADVDA

Not sure what exactly to do with the values produced from the user seed as that is only 1 of the signatures for a 2 of 3 vault
