Whatever guard you do go for I'd at least get one with the correct hole pattern for a '61... and I'd get one with the truss access 'notch' as well just for authenticity.
I'd say the guard you have with the '63 and on hole pattern and '71 and on absence of notch can't be any older than just that ... '71 earliest. Likely later.
I still think mint is the classic look .... with the right pattern and notch.
Either way it looks beautiful guitar and if it plays great and sounds great there isn't much more to say. Keep it.
