Pictures are needed...
The records of the old canoe companies don't exist except in a very few cases, but given pictures and the word "champ" someone here may recognize what you have.
Old Town 9928 doesn't match your canoe length-wise-- and Old Town never put the name of the model on the stem. For the record, OT 9928 is a 17 foot CS grade HW model canoe, with closed spruce gunwales and oak trim. It was shipped to Milwaukee 2/15/1909.
I put the word "champ" into the search function above, and got a query by Jimbo regarding the same canoe... only the s/n was 992B, with a "B" instead of an "8".
Again, pictures would help...
