Side note,, The primary shown there is from the 30s to early 50s.. Late 50s-Early 60s was still sheet metal but a more curvy style.. 65-up was cast and the cover no longer looked like a Derby nut the name stuck.

Knew it was a Derby cover but never got the connection. I am getting older, but I guess I'm not old enough. Thanks for pointing this out. I will add it to my cesspool of useless information!

That must be one of those European ones, where it's mounted on the right side.

"55 up had a compensator assembly, therefore the change.
Some early derby covers had a raised nipple in the center of the dome.

Can I have a peak at the rasied nipple in the center of the dome?  Just a peak?

All I can do is ask of the "owner" of that peak!
Hold your breath until I get a definitive answer!

I can't believe you guys are gullible enough to buy into that hat theory. Everyone knows the real reason:

Granted, I've just cracked my second bottle of Jameson's...but why is the primary backwards but the wall photo correct?

Grumpy fixed the primary cover but messed up the photos on the wall.

Since it's a Hog, it should have been a Pork Pie Cover.
