7th armoured division patch datation

[Lemataf]

Hello there,

I found this “desert rats” (one of my emblematic british unit since I was very young ... probably a colateral effect of me having watched the movie of same name ) divisional patch with a little lot of ww2 british patches, at an Arms Fair, when I lived in UK. Now I know that this insignia has kept being worn far after ww2. When from would you date it?

Thanks & Best Regards,

JD
