why do you want to do that mate??? Im looking at the bottle and the letters are pretty much stuck straight on....there is no need to delete anything from what I can see. Looking at your model you seemed to have made an extra 'lump' around the middle....this isnt needed mate. Just make the bottle as one...create the letters and attach to the bottle. from what I can see the jewelry part is a seperate component and is placed over the top. I have seen this before on special bottles of wine/bourbon.

cheers bullet

EDIT : LOL just realised its a liqueur...LOL so I have seen them before...
