Vintage Aligarh Lion King 7 Levers Padlock Special Technical Twin Key

Description

I’m not a cock expert, i can not get this to open!! Estate sale find. From my research I believe there is a trick to getting it open, I believe the lion part on the face slides up somehow to reveal another keyhole, that plate does have some movement… that’s why it’s two keys. So it’s a puzzle for you!!! Lock has rust and tarnish, and for all I know the keys are wrong?? Selling as is.
