I was lucky enough to score this mint condition Simpson 260 Series 7 (1981 Vintage) on eBay, for the princely sum of £30. It came complete with the original Simpson outer case and test leads. The meter was in such good condition I doubt it left the case much at all.
Simpson in the USA, have been making the 260 series since 1939, even today it has not really changed in appearance since the Series 1, you can still purchase the meter as a Series 8 for around $300.
There is one issue with the Series 7 , 8 though!
Previous versions of the 260 used the 4mm female sockets which all multimeter's use today. Yet some bright spark decided in 1980, that using a reverse banana connector or reverse insulated, were by the meter side is male and the test lead end is female was a far safer option. The rational behind this was, if you had the meter connected to a supply under test, if the leads were disconnected, the tests lead plug end maybe be electrically exposed to the user. Thus increasing the potential of electrocution, the meter is rated at 1000v AC/DC after all. This is exactly why we have shrouded test lead plugs today and only the cheapest test leads do not!
While the meter did come with the original perfectly serviceable Simpson 00043 reverse insulated test leads (reverse banana). They are not the best quality at $35, and are probably not even on par with cheap Chinese shrouded leads on eBay.

Other situations arise also, say if I want to use one of my own test leads. After a lot of searching various forums etc, no ideal or easy solution came to me. Until I stumbled upon a female to female adaptor made by Multicomp. While they are nothing more than a insulated brass ferrules, they solve the problem.

You Can either leave the adaptors in the 260...
Or on the test lead...
If you want a snugger fit you can add some heat shrink.
