WW2 Irish Regimental Badges

[sccollins07]

Hello all! I am new to the forum, and I am in possession of three cap badges from Irish regiments: one Royal Ulster Rifles badge and two Royal Irish Fusiliers badges. Having perused the forum, I am fairly confident the RUR badge may be authentic, and one of the two RIF badges is a fake, but I am uncertain about the second RIF badge. I assumed it would be a fake as well, due to the absence of sweat holes, but also saw what may be possibly places they were filled in.

I have attached images of the three badges below in the order above, RUR, fake RIF, and possibly real RIF. I appreciate any advice, thanks!
