Wheel diameter question

[Stellan Bojerud (RIP)]

Thank you dear friends! This has helped me a lot!

Thanks to Bill I got Gander´s "Bofors book" - which has several errors but also with a lot of correct info.

No, Tony, I did not know of these Budd standard wheels on Bofors guns - but I suspected it. That was the cause why I wrote the question.

This picture is interesting. To the left we see the five spoke (front)wheels we have been discussing. To the right a later type. The brakes were on the back wheels (right on photo).

The gun is the original m/34 owned by Bofors and used for trials and demonstrations. From the beginning this carriage had four five-spoke wheels.

My guess it that they put up new back wheels because 1) the brakes had been damaged or 2) brakes had been improved.

So please comments on the "new" wheels.
