Security tags needed

[Nathan Schwartz]

We have an old 3M security gate in our local history room.  It is model
ET3000 and was purchased 10 years ago.  The supply of echo-tags that we
apparently
purchased at the same time has been exhausted and 3M no longer sells them
and had no
suggestions about a supplier.  I was wondering if anyone might have used
this system in the past and have some echo tags that they no longer need
and might be willing to sell.   We have tried the radio tags that Gaylord
sells but these do not work either.  Any information or suggestions will be
appreciated.

Thank you
