ENS - Release after grace period - Original fee

Hello - I brought a number of names back in 2017 using Metamask. I think transferred each name purchased to individual wallet addresses on MEW (both owner and resolver). I did not renew the names so they have today been released (or subject to premium price).

Question - I would like to claim back the original eth that I steaked in 2017…but I am not sure what is meant by “owners wallet”…Is this the MEW wallet that I transferred the name too - or the original metamask wallet that I used to pay for the original steaking fee…

It’s the wallet that owned the name in the registrar before our recent migration earlier this year - so in the case you describe it sounds like it would be the individual wallets you created for each name.
