Attach 1 - Brand Name JA Redacted.pdf

This document is a Single Source Justification (Simplified Acquisition) for a Dorr-Miller Transfer Case to be used in an Oshkosh truck Model HB2718. The specific transfer case (55000A Dorr-Miller P/N 3474438) is a three-shaft 2-speed unit with all-wheel drive and automatic locking differential, required for the 92d Contracting Squadron at Fairchild AFB in Washington.

The justification explains that this is a brand name requirement because Oshkosh originally owned the Dorr-Miller brand, and only M-B companies will sell through Small Business distributors. A market research effort using NAICS code 336350 identified 488 contractors nationwide, with narrowed searches revealing 6 contractors in Washington, 4 in Idaho, and 2 in Oregon. An email to 8 vendors yielded 2 responses, with one contractor confirming interest. A Sources Sought notice on SAM.gov on 19 February 2025 received one small business reply. The Contracting Officer determined on 17 March 2025 that a single source is reasonably available, with future market research planned to explore alternative transfer case options.
