Taps for Commando

Hi,
lost my baggage with tools that i need to buy again.
Please, what are the measures of the taps for:
-cylinder head bolt (3/8 ???);
-ROCKER END PLATE SCREW;
-EX VALVE COVER STUD;
-OIL FEED BANJO BOLT;
-BOLT - OIL JUNCTION BLOCK;
-CHAINCASE FIXING SCREW (1/4" ???).
Thanks in advance.
Piero

Most of these bolts are Whitworth sizes. If this is for a tool bag when out riding, I like to carry adjustable cresent wrenches (one small, one larger) to handle most bolt sizes at the side of the road.

I assume you mean the head/wrench sizes for the nuts/bolts, and not the tap sizes to create/chase the threads?

ROCKER END PLATE SCREW - 7/16 wrench, 1/4-20 tap
-EX VALVE COVER STUD; 7/16 or 1/4 WW wrench
-OIL FEED BANJO BOLT; 5/16 WW wrench, I THINK this is 17 TPI, but I don't have a 17 TPI thread guage and neither my 16 or 18 fit.
-BOLT - OIL JUNCTION BLOCK; 3/8 WW wrench, 20TPI
-CHAINCASE FIXING SCREW - if you mean behind the crank sprocket then 7/16 wrench, 1/4-20 tap

Should be lotsa info in the Norton Andover parts manual that anyone can easily look up.
