Hello,  I have bought several Rolmonicas for resale here in the UK
and so far they are all the same.  However, one has arrived which
is different.  It has a tin plate lid to it and is not sealed as the
others are.  In fact, it doesn't play if the lid is closed.

When was this one made, in relation to the more usual?  Before or after?
And what year would that be?  Are they common in the USA?  Any other
thoughts?
