As someone else pointed out,
whilst it has the "look" of a Pearson it does not seem to appear to be in any of the Pearson catalogues
& indeed does not include a "CAT" no. in the spec writing.
The spec writing does look like that on other Pearson bows, but ....
The "Impala" looks like other Pearson logos.
It has the look of a Pinto on the back & ? on the belly - e.g. 2 designs spliced together vertically in the handle.
Pearson worked with (& made bows for?) Howard Hill who had a "Impala" model
- purported to be a Pinto with "bamboo" limb cores rather than maple.
What limb cores does this have?
If bamboo, could it be a prototype for Hill?
Could it be "Leisure Group" owners using up old stock by making "Frankenbows"?
