I believe most all 260s are 50uA movements (which gives the instrument 
its 20kOhms/V rating), but around Series 6-7-8 or so, the basic 
D'Arsonval movement was replaced by a taut-band movement, and then 
back-to-back protection diodes and other electronic "improvements" added 
later.

My Series 3 has a Series 5 movement (a replacement somewhere along the 
line), on which I've managed to scramble the rear hairspring while 
trying to Scotch-tape out some crud between the armature and the slug. 
Shoulda left well enough alone (or heeded the - too late - fishing-line 
suggestion.)  Aaaargggghhhh!

There are a wealth of 260s on ebaY at any time, but you may have to ask 
(as I have, several times), "What's the Series # under the Simpson name 
on the meter face?"

Good Hunting!

All else aside, RF to the other fellow's antenna is what counts.
