1923 sports rear axle

[Tony Betts]

Hi jonE,

I may be able to prove it's a 1923?

Have been comparing centre banjos this evening. And noticed my pile of 26 to 29 banjos have an oblong casting on them.

So thinking how early did this block come in, I turned to a 1924 axle I have. Pic below.

The 1924 axle also has this block.

So I take it, it is only the 1923 centre banjos that don't have it?.

Here is the pile of 1926 to 1929 banjos.

All have the oblong casting.
