Both Minden and QMS Militaria have on sale badges that are supposedly of the Indian Army Educational Corps in use from June 47-Aug-47. However the badge they shown is according to me not the correct version. This one according to me is post-Independence

I've dealt with both Rod Flood and Mike the Quartermaster for many years now and am sure its because they do not know about it. Ive written to them about it.
The June-47-Aug 47 badge has "Indian" in it...Will try and attach a pic of the one I have...
