Pre 1922 152nd, 153rd and 155th Punjabi titles

[cymro]

With all the confidence of a kitten wandering into a wolves-only night club I'd like to ask about where and with what likelihood of success one would look for the pre 1921 shoulder titles of the 3rd/152nd, 1st/153rd & 2nd/153rd Punjabis. I am a Welsh collector and am looking to complete a collection to the 53rd Welsh Division that served in Palestine 1916-1918. In order to be thorough I am looking to include the shoulder titles worn by the Indian units that came in in May and June 1918 to replace the British battalions that had gone to France.

I may be asking for the moon on a stick here, but I'm afraid my ignorance of Indian Great War titles knows no bounds and I wanted to ask the assembled and significant knowledge on here for their ideas.

In short, any thoughts would be greatly appreciated and responded to immediately.

With Best Wishes
Jon
