Lift & Drop button order

Hi, just bought a second hand op-1 and noticed my lift & drop buttons are in a different order to other Op-1 is this normal?

hmmm not that I’m aware of ave you tried them? OG owner may of put them on wrong when fixing them

I’m thinking you’re correct as the buttons work as normal, is there a guide to opening up the op-1 and changing buttons?

this should be the droids u are looking for

Many thanks to both of you for your fast responses:)
