Due to the decreasing role of cavalry in WW1 and growing manpower issues, circa 1917 many Yeomanry were dismounted and re-rolled, predominately as infantry.
The below info and dates are all taken from the excellent Long Long Trail
website.
Hopefully this thread can be used as an index page with information and period photos added to solve longstanding questions on which Yeomanry were rebadged to their new parent regiments.
I fully expect there will be cases of mixed badges worn and even contradictory information but this all adds to the debate so please do post if you think you have some relevant information.
N.B. I’ve purposely not included any changes that were subsequently reversed. However I have included the 1916 raft of cyclist conversions just in case any of these units rebadged to Army Cyclist Corps or others.
Please feel free to point out any errors or mistakes to the list.

Conclusions: apparent conflicting evidence as to what was worn on the Tam (see Ayrshire Yeo entry). As a VC winner it’s possible there was an element of regimental politics around the photo of Sgt. Caldwell. Other possibilities are the Ayrshire Yeo retained their badge but the Lanarks did not, or, the Ayrshire Yeo picture was taken soon after the merger and the RSF grenade enforced later
