I have an EXTEL printer made by Extel Corp in Northbrook Ill.
It is a 6 pin dot matrix printer and seems to be a 5 level machine  
probably made in the 70's.
Any info would be appreciated.

Will,
Presumably the EXTEL means EX-Teletype people that started the company.
These dot matrix machines were an inexpensive way to print out the  
latest financial information.
Stocks, bonds, averages, etc., etc.  A modern alternative to the  
"Ticker"
Many of these were installed in newspaper offices and homes of  
investors.
As a Bell technician in the early 70s I installed several data  
channels for use with the EXTEL
printers.  One such circuit at the EXTEL company location in Northbrook.
I also was called out to repair a data channel for an investor at his  
home in Barrington, Illinois

I have no personal experience with the printer itself, but others on  
this list do.

Good luck,
Don
