'30 Model G - Correct Cam and Followers

[Bennet Longman]

I have what I understand is the correct A6/664 cam for my G. If I remember, it can be distinguished by having two separate lobes.

The followers are marked A6/211 but the 1930 parts book lists A6/449 for the Model G. I was told that there is an important difference in profile or other detail between the two versions. Should I pursue the correct ones?

I think the G and all 30's models had a course pitch on the gear wheel ,but this later cm will fit.as for followers didn't the G have roller followers.

The roller followers were only fitted to the 1929 E. I cannot remember or never knew the difference between the std and the G followers but I we have drawings for both and I have had a look at them. However I am stuck in a hotel in antananivero so only have my mobile to look at them, which isn't easy. The feet appear to have the same profile and position, the difference is that the G ones are lighter and slimmer. I will have another look when back home next week.

Thanks Roger, would be interesting to see the detail on the drawings if you have them. I remember talking to Paul Meredith about them at an AGM a few years ago but the details are hazy. I have an idea it was about the ground radius of the follower pads.
