Unfortunately this is about as close as I have been able to come to VMF8. It details how squadron designation VF-8M came about and what it later became which was not VMF-8, but rather VMF-2.
"VMFA-211 can trace its lineage to 1 January 1937 when Marine Fighting Squadron 4 (VF-4M) was activated at Naval Air Station San Diego, California.[1] Although it was the second time a VF-4M had existed, the previous one was decommissioned in 1931 and it was not considered the same squadron. The squadron was decommissioned in 1933 but was recommissioned as "VF-8M" in 1935. On 1 July 1937, VF-8M was re-designated Marine Fighting Squadron 2 (VMF-2) and by the end of the year, had completely reequipped with Grumman F3F-2s which replaced their F3F-1s and a few even older F2F-1s. The squadron participated in annual Fleet Problems while at San Diego and even played a part in the making of the movie Dive Bomber. Several future Medal of Honor recipients served with the squadron during this period, including Henry Elrod, Robert Galer, and Gregory Boyington. In January 1941, the squadron moved to Marine Corps Air Station Ewa, Hawaii and was re-designated VMF-211 on July 1, 1941."
