Your photo shows the original Bendix/Stromberg box with the exact application printed on the label:

APPLICATION:

Standard Stromberg SF‑1 Carburetors Carburetor Models:

• A‑16221

• A‑18701

• 380021

This is the only confirmed application set for RK‑99.

These SF‑1 carburetors were used on post‑war small engines, including light industrial units and some early automotive applications where Stromberg supplied single‑barrel downdraft carbs.

🔧 CARBURETOR FAMILY CONFIRMED

✔️ Stromberg SF‑1 Series

This is a small downdraft carburetor family used on:

• Early post‑war industrial engines

• Small agricultural engines

• Light automotive applications (limited)

• Stationary power units

The SF‑1 is not part of the BX/EX updraft family and not part of the AA‑1 or BXVD automotive families.

RK‑99 is one of the few SF‑1 kits that still survives in NOS form.
