Help needed - info on NZ broken back shillings

[chasingmonarchs 0]

Greetings all-

 

I just found and joined this forum earlier today.

 

I collect British empire pre-decimal issues, and I'm currently working on my Fiji and New Zealand sets.

 

Krause has two "broken back" shillings listed for New Zealand - 1942 and 1958.

 

How can you tell a "broken back" shilling from a "normal" shilling?

 

Does anyone have a detailed picture they'd be willing to share, or a write-up describing the distinguishing diagnostics to verify if you have one? I'd like to know what I'm looking for so that I can obtain these varieties for my collection.

 

Thanks in advance to any and all who offer help-
