Quick . . . date this black/white  photo of a moving vessel from the archives?   It appears to be moving slowly.

See the bollard just forward of the vessel?  It may be moored along a lock approach wall.

Someone more familiar than me with locks and terrain along the canal might know the location above.   

On the raised bank beyond Number Seven is a row a billboards.  Let’s zoom in there.

The ads are for some kind of ale, Ford, Heinz, Utica Club, gum, and something else.  Know the year of the Ford depicted?

I’d say it looks a lot like this ad.  And Prohibition ended in December 1933.

New York DPW shops in Syracuse did build a Number Seven, completed in 1931, per the entry below from the 1933 Merchant Vessels of the US (MVUS) list.  By the way, the 210 is gross tonnage, a volume measurement.  It was 110′ x 25′.

So I’m placing the photos as taken in the 1934 season.  Number Seven disappears from MVUS after the 1959 issue.  Here’s a photo of Number Seven in color and marked as 1965.  What happened to it?
