[Healeys] BN2 screw in the center of the dash

[Curtis Arndt]

Hi Bob and Joe,

Just a quick correction, "Pozidriv " screws were never used on AH 100s,
BN1/2s.

The four marks on the head of these 10-32 screws were there to denote UNF
from "Whitworth" during the changeover to the Unified screw thread forms in
the 1950s.

I've attached a page from my vintage Machinery's Handbook which illustrates
this fact.

Cheers,

Curt
