Interesting,
Those rods are NOT 91A rods, the caps are but the rods ain't ! The rods are 48's!!
When you've had a bunch of these flathead parts in your hands, you can tell at a glance the rods ain't 91 or 21A which are much beefier where the beam meets the journal area. The earlier rods (like yours) are petty slender down there.
All the rods in your earlier pic are 48's, they all got 91A caps on them?
I've seen mixtures of 21A and 91A rods in a war time flat motor, but not swapped caps.

I guess all sorts of odd things went on at Dagenham during the war, it must have depended on what they had in stock. I will check the other rods for cap numbers.

Only 3 of the con rods have 91A caps, the rest match the rods. As you say, all the rods are the slim 1937 style ones not the later type with strengthening ribs near the big end. I will add a photo with a comparison against one I removed from a wartime US 239.

Ford UK Rod on the right.

I hope my pilot motor has rods a bit thicker in the uppers than these pics show.

Will know soon when I pull it out .

This picture shows two 21 Stud Ford V8 Heads that were for sale at a recent Swap Meet. I believe that the one with the Firing Order cast into it is from the British Ford Pilot. The other "plain" Head is probably Canadian, from a 1937 or early 1938 Ford V8. What do other Barners think?

"Nervous Bob Froch ought to be able to help you out.

I have some parts from a 21 stud motor that might be useful to you, I'm in the Midlands though, (Solihull), Bob is over your way.

The lower head is a Dagenham manufactured head.

Thanks for the link mart.

Cleaned up half the Rods this evening and one of them has a different little end to all the others. Is this an earlier version (although it has the same forging number) or has a machining step been missed? Note that the rod on the left is on with the 91A cap.

Alastair, don't quote me on this, but I think that is the factory method for balancing the rods. Hopefully someone will confirm or refute.

Marks in lower picture are I think Brinnell hardness tests. I knew Ford did 100% Brinnell testing on pitman arms and such...never noticed it on rods. I wonder if Ford tested all of them and I just haven't noticed?
