Burroughs direct adder???



#2

I recently purchased (very cheaply) a burroughs direct adder machine from a thrift shop.It is exactly like the one pictured in the hp museum under old models adding machine.. it has a serial # on it and is in working condition.. Would anyone have any idea what the price of this could be? Is it worth the time to keep looking it up.. I believe it to be made in the early 1900"s???? Thanks for any info.
