New York Stock Brokers: Wayland Trask & Company or Walsh, Tailer & Company?

A check of the firms doing business at the New York Stock Exchange during the 1898 tax period included two firms that would have abbreviated their names "W.T. & Co.":

• Walsh, Tailer & Company
• Wayland Trask & Company

Wayland Trask was a broker who held a seat on the NYSE throughout the tax period.  Walsh, Tailer, however was comprised of several brokers, including Edward DeWitt Walsh and James B. Tailer.  Their firm did not trade throughout the tax period (they can be found in the 1900 and 1901 lists) and was not listed as a firm in the 1898 or 1902 lists.  Starting in 1902, however, most of the brokers from Walsh, Tailer moved to the new firm Tailer & Robinson.

Further below is found a couple of broker's memos for Walsh, Tailer, showing unambiguous CDS handstamps.  Immediately below is a cancel with only the initials "W. T. & CO.", plus "N. Y."  

W. T. & Co.

MAY

1

1901

N. Y.

Was the stamp above canceled by either Wayland Trask or Walsh, Tailer?  Since N.Y. is present in the cancel, the stamp likely was removed from a broker's memo; as the memos below show that Walsh, Tailer was using a CDS (the stamps above and below were canceled in May 1901), my bet is that the cancel above is that of Wayland Trask.  We'll need a Wayland Trask broker's memo for confirmation.
