Royal Engineer Shoulder Flash - Which Trade/Branch ?

[MERLINV12]

Hopefully someone will have come across this Shoulder Flash before, and can tell me the trade or branch of what I think is the Royal Engineers.

TIA.

I am far from being expert, the colours do look to be RE, I am pretty sure it isn’t a Trade badge and is more likely to be a unit identification flash, such as a regiment etc.

I don’t think it is WW1 insignia.  More likely to be WW2.

I agree with Frogsmile, if anything it is WW2
