+I am editing this post to reflect my latest discoveries regarding L & M100 manual chassis that will accomodate 10 busbars
.
-To add further to my above comment:
+The L133 manual chassis I originally spoke of is of different design than any other Hammond chassis I have seen.
+The actuators, contact boards and terminal strip are ALL made of plastic - Hammond chassis usually have bakelite boards, etc., - interesting....
-I have worked with many M100-series manual chassis.
NONE of the *M100* chassis I have worked with will accomodate 10 busbar contacts.
+That is, _until recently!_
-I have also worked with many L100 manual chassis
.
-The ONLY L100 manual
chassis I have found that will accept 10 drawbar contacts is
the L133.
+I opened both an M103 and an L111 recently and they _both_
have room for a tenth busbar _and_ room for contacts for the tenth busbar, if installed
. These
chassis are the same as
the L133 I described above. All plastic guts
.
-This particular L133 manual chassis
I speak of is of different design than any other Hammond chassis
I have seen
.
-actuators
, contact boards
and terminal strip are ALL made of plastic -
Hammond chassis usually have bakelite boards
, etc.
, - interesting...
.
+I checked my history working with these spinets and found that 1964 and earlier used the bakelite boards and would not accomodate 10 busbars.
I have _not_ been into a 1965 vintage spinet
.
The last two models I opened up are 1966 vintage.
+
+So
, it was obviously a production change in 1966 (for sure)
and possibly 1965, where
Hammond added this "feature."
+
+To find out if your L or M100 has such a
chassis, from frontside
, remove the metal L
-shaped cover from the lower manual chassis assembly (two screws at each end)
.
-I added foldback
to this particular chassis and I sold it - so I cannot give any more particulars about this "unique" chassis. I do
have a photo
of the backside of this L133
chassis but I have no idea how to post it here
.
+If the terminal contacts are mounted
to a black, plastic board (as shown below), chances are you
have one
of these 10-busbar
chassis.
-I can only agree with the original post in that the ACTUATORS for M, L100s DO have 10 slots
.
-BUT, regarding adding a tenth contact, not all the L, and
/or M100 chassis have slots for 10 contacts!

-All I can say is, beware of buying an M-, or L-100 with hopes of adding a 10th set of contacts and/or a 10th busbar.
-You should find out what's inside the chassis before you buy!
