Hi All:

At John's request, I am posting this. On a recent trip to
Ken Gartland's, he gave me these. They are print hammer
bumpers made here in Canada for the Marsland/Leigh ASR and
KSR 33's, and presumably would fit the model 32's as well.
Unlike NOS american ones, these were made with a different
material, and as a result never went gummy. They are,
however made to the same specs as the US ones and will fit
all 32's ot 33's. The two of these have a slight mold flaw
on one side, but this could be corrected easily in
production.
Though it doesn't show on the photo, remember that the hole
in them steps back inside to hold it on when it snaps onto
the hammer.
John wanted me to post a photo in case someone wanted to
try to make one for themselves:

Another member of the list has been sent one of these, and
is going to try to get them duplicated by a company in the
US, ensuring a lasting supply. They needed a good non
deteriorated sample to go from. Stand by for news from him
if it is successful or viable.
Sadly, these are the last two known of these to still exist
here, so they may very well be the last two undeteriorated
hammer bumpers in existence!
Of course as we all know, a quick fix is to place a 3/4
inch length of tight fitting vinyl tubing over the hammer,
but, Oh wouldn't it be wonderful if this attempt at making
new ones using these as a template is successful.
More of the story of Northern Electric, then Marsland and
finally Leigh producing teletypes by license in Canada on
my KSR-33 video description on ebay:
http://www.youtube.com/watch?v=aMvs1t1CEH8
or as follows:
"Leigh Teletype KSR-33 Demonstration - Telephone Museum of
P.E.I.
Many don't realize it, but some teletypes were made in
Canada under license from Teletype Corp.; first by Northern
Electric, then by Marsland Engineering, which was then
acquired in 1969 by Leigh Instruments who continued the
manufacture of these machines. This was to get around
import duties and taxes at the time which doubled the cost
of a teletype imported from the US.
This is an KSR-33 made by Leigh in the 70's. I acquired it
in 1975 from Island Tel who gave several surplus machines
to fellow ham radio operators, used it for a year as a
computer i/o device, then loaned it to a friend. He used it
for a year, and for the next 20 years, it was stored in his
barn under less than ideal conditions.
When my friend heard I was looking for a model 33 for the
museum, he reminded me about this one, and the next weekend
brought it down. Barn storage had been cruel on the
machine.
The top cover had been broken in, and squirrels had been
living in it, leaving it littered with parts of spruce
cones and other seeds. In addition, the storage had been
very damp resulting in a lot of rust.
The next few weeks were spent removing rust and replacing
damaged parts, the broken cover, etc.
However, as you can see this old baby has been quite
resilient, and with some major TLC is now working again. It
is a nice feeling bringing something like this back to
life!
Here, you see it printing out text from the Internet using
a program called Heavy Metal via a Telebyte M65A interface.
The first while, it is shown with the cover down, then for
a minute or so with cover open, so you can see its printing
action, then finally in a shot panning around the museum to
other equipment on display in the teletype area.
You can also see a model ASR-33 on display, a model very
similar to this one, but with the ability to generate and
read paper tape. Videos of that machine and two of my Model
28ASR machine are also viewable on my YouTube channel.
I will be doing additional cleaning of the discolored
plastics as I have time.
Leigh Instruments acquired Marsland Engineering in 1969 as
part of an expansion. Leigh closed their manufacturing
facility completely in 1983 to concentrate on other
ventures. Unknown to many, Northern Electric manufactured
these for a few years before Marsland started building
them, but the quality was poorer due to inferior hardening
of metal parts as compared to these and those made by
Teletype themselves. Note Leigh's white on blue nameplate,
as well as the small Island Tel nameplate on the cover.
When I was doing this video, I didn't quite have the
printer inside the case properly, and as a result with the
top cover down, the paper was jamming somewhat. This was
fixed as the video uploaded. That is why near the beginning
of the video, you will see me fiddling with the paper
before opening the cover. This is not normal and has been
resolved.
My thanks go out to Ken Gartland of Nova Scotia, an ex-
CN/CP Telecommunications service technician for going over
this machine's printer after I had it operating and setting
it to meet factory specs with his test set."
