Hi Trigger 1975,

Thank you very much.

Jim Burton graciously responded to me.

He confirmed that mnemonic phrase was only for Multibit HD as previously suggested in several posts here by different members. Phrases length were 12, 18 and 24 words. So, that's not the case with me having 16 words only.

I made more searches and find that 16 words could be to old Bitcoin recovery password phrase. I tried to see if my words were there:
https://github.com/blockchain/unused-My-Wallet/blob/master/mnemonic_words_v3.html

And yes, they are!

It happens that along with my paper notes in the same notebook as my 16 words phrase, I have a login name and password for Blockchain, so at some point I had signed up and I guess this is where I got the 16 words phrase. So, it's not related to my Multibit wallet from which I therefore not have any mnemonic phrase to recover my bitcoin.

As previously stated, my Multibit classic wallet is in laptop that is dead / broken but I still have it.

I contacted Dave at https://walletrecoveryservices.com who responded to me, but he works on lost password / seed phrase etc. and not on broken laptop so I don't think he would be able to help. He asked me for my seed words, since there are not related to my wallet, this won't work.

So, I need to find a reliable and trustworthy bitcoin recovery service for broken laptop. I am not going to rush into that, I need to do extensive researches. If it happens that a member her knows somebody who can do that for me (I live in London, UK) please let me know.

Thank you all again for your kind time and helpful input.

Nicky
