Help With Military Group Photo Please

[Treetotal]

Hi...Would anyone be able to give me a date for this photo and any other relevant info please. It's from the East Yorks. area I believe. I don't think a scan of the cap badges would give any more info as they are blown.
Thanks for looking.

Have to wait for Jim 1 to pass your way, but I think it must be post WWI but not by much. Officers rank badges were on slash cuffs at end of sleeves in WWI. The officer has plain sleeves.

Thanks for that Regorian...very helpful

The sergeant, next to the officer, appears to have an emblem over the stripes on his right arm, so could be Royal Engineers, whose cap badge is almost a circle.

The Lance Corporal far left on the second row as you look at the photo also appears to have a mark above his chevron but it could be damage. Thanks for your input Ainslie...it's much appreciated. Any idea on a date please?

Royal Engineers. The officer's grenade collar dogs are one giveaway as is the grenade over the sergeant's stripes (as well as the cap badge shape already highlighted.

Could be late WW 1 officers' rank changed during it.

This is not accurate as officers started wearing rank on the shoulders during the war.  Many also wore ORs tunics and trousers to avoid being picked off as an officer.

The style of hats suggest 1916 onwards whilst the absence of any medal ribbons suggest pre 1919.

Thank you for correction, I believe similar thing happened in American War of Independence, carrying musket too.
