Help - Original Tucker & Sherrard Dragoon

[Long Johns Wolf]

Can one of you initiates help with measurements in either inches or millimeters of the frame of an original Tucker & Sherrard Dragoon, please.
May be, this data has been published somewhere?
For a project I like to have the exact length of
# the watertable (without the locator pins) and
# the bottom of the frame.
Thanks for your help.
