Detaching HP Classic Front Labels

[Les Bell]

I'm restoring a 65 with worn silver trim and have obtained a replacement case top assembly so that it will be good as new. However, the new top doesn't have the "HEWLETT * PACKARD 65" label on the front edge, so I'll need to detach that from the old case and attach it to the new one. Can anyone contribute advice on doing this while still preserving a good cosmetic finish? I'm guessing that a heat gun or hair dryer might do the trick, and with the case taken apart there's no risk of damage anywhere else. Or would some kind of solvent be better?
