1911 Old Town guide question

[Rod Tait (Orca Boats)]

I am working on an Old Town 1911 18 ft. guide. It currently has two thwarts of ash but it is missing the center thwart/yoke? Any photos or thoughts on whether simple thwart or yoke. .

A standard Guide or I.F. model from 1911 would have come with an simple center thwart as shown in the catalog page below. More information like this is available from http://www.wcha.org/store/complete-old-town-canoe-company-catalog-collection if you want more details.
