From the head (front and back) to the pushrod tubes joining about the middle of the cylinder. Everyone chromes them - they were not chromed from the works

He's this scary encyclopedia that needs a jolly good download. The ghost of Edward Turner demands it.

rego plates of that style were used 1946-1951, they didn't have stickers so changed them every few years

Thanks everyone. It's a bike keen friends grandmother and grandfather and she's interested in any info gleaned from the photo.

Yup! Bike next to it has a nacelle which means the photo was taken 49 or later

However the main bike is interesting because it should have a ribbed front tyre as stock! (THAT makes me a nerd) So its been changed out or worn out.

Its also had the mufflers removed and the read guard bobbed

It looks like he was racing or sprinting. Tracks were not as we now know them........

Just found out an update from another family member.

It turns out they got engaged in 1949 and he sold the bike to buy her engagement ring so that pins the picture to about 1948-49. He bought another bike a few years later.
