This undated catalog is circa 1908-1910, based on the Old Town Otca model offered only in 16- and 17-foot lengths. The 18' Otca first appears in Old Town's 1911 catalog.

This undated Peterborough catalog is accompanied by a letter dated May 5, 1936, and a 1936 outboard motors price list.

An identical copy of this catalog was accompanied by a letter dated March 1928.

This undated "Nineteenth Catalog" is likely circa 1918-1919. I have another copy that is identical except that new prices were printed and pasted over the old prices.
