[CW] old J key

[k8omo at juno.com]

Hey group
 Without offending any one I refer to this kley as a J key 
without any numbers after it .
 I picked one up a Lionell at local hamfest last weekend 
but the strange thing about it was there is a E. F Johnson
key on the Lionell base , is this possibly a replacement 
or did it actually come that way ? Never seen one before
, it looks original ,no screws scratched or the base either .

opinions please
