Serial Number 1877625 was reported as inaccurate.

Note: The information on 1877625 corresponds to the
database information as far as I can tell. But
if there were almost 77,000 of these made, why are
there only 5 noted in the database all within a
very close serial number range ? I also note that
they were suppose to have been manufactured into
the 1920"s. Were they still producing 18S Bunn
Specials that late ?
Thanks ......Joe.
Curator Response: The images are contirbuted by users. And yes, the 18-Size Bunn Special was manufactured into the 1920s.
