Mercedes Neiman 120 ignition lock assembly

Dear friends

Do anybody knows to which Mercedes belongs this Neiman 120 ignition lock assembly?

Best regards

Found the answer.  This ignition lock assembly belongs to a Mercedes Benz w113-250SL

But which 250SL?  Early or late?  The late ones had a double sided key, while the early ones had a single sided key.  In addition, the actual electric switch on the rear is very different between the two, as well.

Gents,

This is a steering lock for the 230SL/early 250 SL up to VIN 002979,
one-sided key.

If you want to use it for a late 250 or 280 SL
you have to remove the lock assembly first (drilling out the bolts) and put in a /8 ignition lock instead.
The electric switch (not present on yours) can be exchanged between both.

... and ah, yes.

The steering lock is almost useless without its key.
Almost ....

Achim, you may want to do a little more research on the electric switch part.  There were two different versions.  The one used on this early ignition lock was connected to the cars wire harness with individual eyelets and screws for each wire.  The electric switches used on the late 250 and all 280 models was connected to the cars wire harness with a round phenolic plug that pushed on the the electric switch.  They are interchangeable in that they both may physically mate to the lock assembly, but they're not interchangeable in a usable sense, as one would have to change the cars wire harness or entire plug to make one or the other work.  Please see pictures below denoting early and late style.

Yes Aaron,
Thanks for the advice.
I knew that already... 
since I have got also a 114015 (my forum's name) I have seen these obvious differences before.

What I wanted to say is that the core steering column lock "Neimann 120" is the same for the early Pagodas (230/250, part number A000 462 2830) and the late Pagodas (250 late/280, part number A000 462 5930),
only the tumbler assembly - and yes, you are right the electric starter switch part behind are different.
The latter are easily exchangable - as you mentioned,
but the tumber assembly is not so - at least not for the early version, and replacements therefore have never been available from MB.

Best,
Achim
