Question about Order of Malta

[westfale]

Hi!

 

After purchasing this interesting cross of the Order of Malta there is one question left for me: why this cross did not have the "normal" rearside inscrption "A.D. MCMXXIII"? I have seen some other pieces like this looking at some sellers, but why this cross is different or who made it and at which time i don't know, Does anyone have more information about this and could give me some details?

Thanks for your help!
