Steve, since you are THE Edison Reproducer expert, how do you explain that 
Edison kept making Reproducers with the adjusting arms long after all the 
machines had alignment pins and the securing screws? I cannot imagine a 
scenario that results in adjusting arm equipped Reproducers being produced with 
high serial numbers so much later than the clips were phased out.

Hello Al,
 
Thanks for the wonderful compliment.  I am pleased to have this question and 
very thankful for the recognition, it means a great deal to me.  I enjoy 
reproducer questions.  Much of my research is done by examples I have seen on 
eBay and with friends sharing so any input is appreciated.  Since I do not have 
access to much written reproducer material much of my work has been like 
putting a giant jigsaw puzzle together.  I never mind learning so any 
corrections are appreciated.
 
If you had a carriage with the clips and wanted to upgrade from an automatic or 
early B without the notch and you did not want to upgrade the carriage you 
would need an armed C.  This is why I believe you see the armed C into late 
1906 or early 1907.  I have seen a number of machines with clips and an armed 
C, I have seen one machine with the carriage updated and the lug holding the 
adjusting screw removed.

The more detailed answer:
 
A20189 is the highest serial number of armed C I have seen so far.  If you had 
a carriage with the clips and wanted to upgrade to a C the arm was necessary if 
you did not upgrade the carriage with the centering pin.
 
I believe the Model C is found with the arm sporadically into early 1907.  The 
new top stamped REPRODUCER appeared by 108,000.  I believe the arm was retained 
for two reasons, first the Edison factory never wasted and parts got misplaced 
and found later on, secondly if you have a carriage with the clips and you 
wanted to upgrade that carriage to a Model C the arm was necessary to easily 
have the stylus in the position where it tracked properly.  I owned a suitcase 
home that had a carriage that originally had the clips and the four holes for 
the screws, but the lug that held the adjusting screw was machined off and it 
had a centering pin and set screw.  From this I assume Edison updated the 
carriage and I assume there was a charge.  To upgrade a suitcase home and not 
modify the carriage an armed C was the easiest way.  
 
The B to K share serial numbers and the B replaced the automatic around the 
summer of 1901.  The early B does not have a notch for the centering pin until 
in the 17,000 range, but some in the 18,000 range is found that way also.  The 
C joined in around 25,000 and the D around 30,000.  When the Gem started to use 
the B reproducer it did not have the arm.  B reproducers from 40,000 to around 
105,000 that were used on the Gem do not have the arm and the word Reproducer 
is not on the top.  For years the armed C puzzled me since the Gem B did not 
have the arm and the armed C was made for so long.  This gave me the idea that 
Edison kept the armed C for a reason as well as using up old parts.  
 
Armed B reproducers above 40,000 are not common, but I have seen them on 
concert machines and an Edison Bell Duplex.  The reason Edison is so much fun 
to research is because of all his varieties.  
 
Al, Ron, Bill, Dave, Anthony, and many others have been extremely generous in 
sharing reproducer photos and information with me and I really appreciate it so 
very much.
 
There are four types of the armed C:
 

The first Model C has a blank weight, an arm, and the serial numbers by the 
letters and a stepped mica diaphragm that goes from around .003 to .009.  The C 
appeared around serial number 25,000 and always had a notch.  The B got the 
notch around 17,000.  

The second C has Model-C added to the weight which happened in the 30,000 range.

The third C has holes added to the weight which happened in the 70,000 range.

The fourth C has the serial numbers around the sound tube and A20189 is the 
highest serial number I have seen of this type so the armed C appeared 
sporadically into early 1907 or the end of 1906.  Edison never wasted and often 
earlier parts are found on later products.  Just before 400,000 in the 
390,000’s both the recorder and the reproducer began to get the serial number 
around the sound tube on the ledge.  
 
There are three main types of the copper diaphragms found in the C.  The first 
one is more smooth like the early large diaphragm found in the flat H weight 
model L.  Photos will be sent on request.  It appears the first copper 
diaphragms had the eyelet cemented in with Stratena, unless Edison forgot to 
solder some which I think is not likely.  The first eyelets in the copper 
diaphragms were the nickel plated ones found in the mica diaphragms.  There are 
three patterns of the smooth ones and one that appears more brass than copper.  
Ron told me that Edison cut the top of the reproducers so he could put sand 
grains on the diaphragms to 'see' how different patterns affected the sound.  
 
There are two types of the corrugated common C diaphragm, the first one was 
like a child's swimming pool in that it was stepped down, the later one is flat.
 
Around 2,119,000 of the small tops were made from the first B of 1901 until the 
CHK's of the 1920's.
 
Around 615,000 of the 2 and 4 minute recorders were made from the new style 
recorder of 1901 with its weak aluminum cutter with tiny arms to the 2 and 4 
minuter recoders made in the 1920's.  From around 1913 on the 2 and 4 minute 
recorder has the same style of stylus holder.
 
Around 309,000 of the diamond C and D reproducers were made.
