 This Division of the Adjustment Board has jurisdiction over the dispute involved herein.

 Parties to said dispute waived right of appearance at hearing thereon.

 The Organization maintains that Carrier violated the Scope Rule of the Agreement and specifically, a Memorandum of Understanding dated April 10, 1952. That memorandum states:

The Organization points out that the Memorandum of Understanding specifically precludes Carrier from purchasing partially or completely wired relay cases and instrument houses on a pre-existing signal system. In its view, since the complete railroad has been signaled since 1952, the present dispute involves pre-existing signal systems. Therefore, it is the Organization's contention that th reasons, the Organization asks that the Claim be sustained. It seeks appropriate hours of compensati Waycross, Tennessee in February 1985.

 Carrier, on the other hand, denies that it violated the Agreement. It asserts that there is no rule which prohibits the purchase of pre-wired instrument houses for subsequent delivery to the CRR property for installation. It further contends to have pre-wired components assembled by its forces. Carrier concludes that the parties agreed that the Scope Rule did not include the assembly of signal and communication equipment for new installations, but did include installation of the equipment aft
After careful consideration of the whole record, the Board finds
 itself in agreement with the position advanced by the Carrier. Carrier has
 produced several Awards of this Division regarding pre-wired signal houses
 and instrument cases. (See, for example,. Awards 20467 and 18814). We have
 reviewed those Awards which determined that seniority rights to work do not
 attach until the material or equipment upon which the work is to be performed
 is delivered to the Carrier. ,
