Lefever Chronology

This chonology is primarily the effort of LACA member Bob Noble. The numbers are mostly from his collection of Lefever serial numbers. I’t can’t possibly be all inclusive because the factory records have long since disappeared and these numbers are based on the onbservations af Bob Noble and some LACA members who report findings to Bob. You can help out the LACA by reporting numbers to either Bob Noble at: lefeverarms@gmail.com or to the LACA at:LACA@hughes.net. The accuracy of the following data are only as good as the reports we receive.
