 AMENDMENT NO. 2 TO SCHEDULE 13D

         This Amendment No. 2, dated April 30, 2007, to Schedule 13D is
filed by the Reporting Person and amends Schedule 13D as previously filed by
the Reporting Person with the Securities and Exchange Commission on April 15,
2003 (the "Schedule 13D"), relating to the common stock  (the "Common Stock")
of Tech/Ops Sevcon, Inc., a Delaware corporation.

Items 3 and 5 of the Schedule 13D/A are hereby amended and
restated, as follows:



ITEM 3 SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         As of April 30, 2007, Hummingbird has caused each of HVF and
Microcap Fund to invest approximately $656,352 and $484,674, respectively,
in the Shares of the Issuer using their respective working capital.


ITEM 5    INTEREST IN SECURITIES OF THE ISSUER

          (a) As investment manager of HVF, and Microcap, Hummingbird
may be deemed to have the sole voting and investment authority over the Shares
owned by HVF, Microcap, and Tarsier for purposes of Rule 13d-3 under the
Securities Exchange Act of 1934, as amended  ("Rule  13d-3"), may be
deemed  to be the beneficial  owner of 269,475  Shares representing
approximately 8.4% of the outstanding shares of the Issuer (based upon
3,211,021  shares of Common Stock outstanding as of February 13, 2007, as
reported  on Form 10-Q for the period  ended December 31, 2006.) Hummingbird
disclaims any beneficial ownership of the Shares covered by this Statement.
