Dear Mr. Bartz:

      This letter is in response to your comment letter dated January 7, 2015
regarding amendment no. 1 to the registration statement on Form S-6 for
Guggenheim Defined Portfolios, Series 1274, filed on December 16, 2014 with the
Securities and Exchange Commission (the "Commission"). The registration
statement offers the VickreyBrown Double Dozen Strategy Portfolio, Series 1 (the
"Trust"). Please note that the portfolio consultant for the Trust has been
changed from Vickrey Brown Investments, LLC to SAFE Investment Management, LLC,
the parent company of Vickrey Brown Investments, LLC.

PROSPECTUS

Investment Summary -- Investment Objective

      1. This section states that the Trust seeks to provide "total return
through capital appreciation." Since "total return" is generally defined as an
investment return consisting of a combination of income and capital
appreciation, please revise the investment objective to clarify whether the
Trust seeks total return, or seeks capital appreciation exclusively.

      Response: The investment objective has been revised to state: "The trust
seeks to provide total return through the combination of capital appreciation
and income."

Investment Summary -- Security Selection

      2. Step 1 in this section states that the initial universe comprises all
common equities traded on various exchanges. Please specify whether these common
equities include registered investment companies or business development
companies.

      Response: The disclosure has been revised in response to this comment.

      3. The first bullet point in step 3 of this section and the four bullet
points in step 4 of this section are very technical and difficult to understand.
Please revise these statements in plain English. See Rule 421(d) under the
Securities Act of 1933 (the "Securities Act"). In addition, the fourth bullet
point in step 3 states that the securities are ranked on the basis of standard
deviation of analysts' earnings estimates. Please describe how the securities
are ranked on the basis of standard deviation of analysts' earnings estimates,
for example, highest to lowest.

      Response: The disclosure has been revised in response to this comment.

Understanding Your Investment -- General Information -- Portfolio Consultant

      4. This section states that the portfolio consultant, VickreyBrown, will
assist the sponsor with the selection of the Trust's investment portfolio, and
"will also provide advice to the sponsor to help the sponsor provide portfolio
supervisory services" to the Trust. Please describe with specificity in this
section the types of advice which VickreyBrown will provide to the sponsor with
regard to the sponsor's portfolio supervisory services. We may have further
comments after reviewing your response.

      Response: The portfolio consultant will not provide advice to the sponsor
to help the sponsor provide portfolio supervisory services. Consequently, the
language referenced above has been removed from the Prospectus.

      We appreciate your prompt attention to this registration statement. If you
have any questions or comments or would like to discuss our responses to your
questions please feel free to contact the undersigned at (312) 845-3484.

                                                               Very truly yours,
