Richard.....so interesting......at WAR 1941/42 Boehme keying heads and 
Kleiinschmidt perforators were standard equipment.

The Boehme keying head had a snap lever on top to select the automatic W A R

or just dots ready for inserting perforated tape.

If we had a message to repeat we would make a loop from perforated tape and 
run it until not needed.

The tape used in the perforators was oil impregnated.

We also had a row of teletype machines each with a perforator.....different 
tape than the Kleiins used.

An innovative vendor from Boston designed a keying head that would convert 
teletype tape to CW.  While it was a great step forward we already were into

the IBM radioteletype and the CW positions were getting less use.

Since almost the beginning of maritime Morse communications coast stations 
have sent the "wheel" whenever they were not engaged in sending and 
receiving messages.

The wheel sent a repeating message stating that the station was open for 
business and listening for ships.  The original wheels were rotating disks 
with notches used to key the Morse message.  Some stations used amazing 
contraptions of motors, shafts, gears and microswitches to perform the task.

One of these has been preserved at WLO.  Later, punched paper tape was used 
to send the wheel and also longer prepared messages like weather and press. 
Kleinschmidt was the preferred brand of punch.  These looked something like 
typewriters and were housed in beautiful rosewood cases.  Some had Teletype 
name plates but were invariably referred to as the "Klein".  The tapes were 
read by keying heads made my Boehme, Creed and others.  In more modern times

the wheel was generated by an electronic keyboard.

Wheels are rarely heard today.  HLO, HLW and other coast stations in Korea 
still hold forth along with XSG in China.  And of course the KSM wheel may 
be heard every Saturday.

The MRHS has several Kleinschmidts and Boehmes in inventory.  Recently we 
had the great good fortune to find someone not only willing but qualified to

work on these machines for us.  One by one we are passing them through his 
hands.

As of this Saturday, 4 July, a newly overhauled Klein and a Boehme were 
brought to KSM and put into service.  These will be used to send the KPH 
wheel on Night of Nights X on Sunday 12 July.  Today we used them to send 
the KSM wheel to test the system.  They both worked like a charm.  You can 
see them in operation in a YouTube video at the URL below.

When making the loop of tape for the wheel, custom and tradition demand that

LePages mucilage be used to join the two ends.  The problem is that LePages 
has not made the needed item for a decade and more.  We have one bottle of 
the original KPH LePages mucilage left.  But today we also took delivery of 
two new bottles of mucilage that we had to import from Canada!

SPECIAL REQUEST: The other expendable we need besides mucilage is the paper 
tape used by the system.  Actually, we have a lot on hand.  But it is old 
and brittle and tends to break when drawn through the Klein.  If anyone can 
lead us to the paper tape we need or to a company that is willing to take on

a special order we would be very grateful.  The tape is 15/32" wide on a 2" 
hub.

Now... on to the video.  See it at:
