Hello, just a new member now enrolled. Have what I believe is a very early on "white" by some details, have no manual, only a serial number that we believe by magnifying glass reads P(underscored) 21388 in a 5 drawer coffin top cabinet type and has a cast treadle assembly with a stamped April 13, 1879 PAT.Jan (10 or 16) 1803. On the crossarm the letters CBR in old calligraphy scroll. Has delicate red, gold, flowers and leaf designs on the head,also
on the flat resting floor. Have searched many other sites on goggle, and have contacted the 800 toll free white number to no avail with the listed serial number as read under the front slide bar etched into the casing. Need help or suggestions as truthfully verify the vintage of this famil antique! Thanks, granniewhite
