Hi, I'm not aware of any Redditch models ever having a cast swingarm? Do you mean aluminium? Vince

Not aluminium , cast steel alloy.

A mix of steel casting and steel tubing sounds more likely, e.g.:

Later ones seem to be all welded.

What do you mean by standard Bullet, 73A? Indian, Redditch, what year?

The one in the photo is one of our hosts' used items for a '53 Meteor.

Next question, what sort of a hub and brake drum/sprocket do you want to fit in it? IF you have the half-width rear that the Meteor used hub then have a look at the parts book here for the bits you need. Note the three-spline brake drums come in 6" and 7" varieties. The parts books is your friend.

If your rear hub IS something different, I'm not saying you can't put something together with that swinging arm/chain stay, but it might need some clever improvisation as well a a bit of machining.
