Need help id'ing some Buttons CP 2 piece, Harp 2 piece, and Anchor

My buddy that found the Mississippi button brought over some of his collection and asked if I could post these for ids.
Over the next few days I will be posting some of the buttons he has found within the past couple years.
The first 2 are your standard GS Eagle size buttons that both say SUPERIOR QUALITY. One says CP and the other is a Harp.
The anchor button is about dime size and has no back.
I will post more when I have time.
Thanks for your help.

Any idea of age/era? You mean like high school marching band?

The harp button is a United States Army Military Band Brass Uniform Coat Button...suspect the benchmark is Waterbury Co.'s of Waterbury, Conn. That pattern was used in both WWI and WWII. Given that it does not have the steel backing, probably a WWI example.

The CP button is a generic police button with "CP" standing for City Police. What I can find on the backmark tells me both buttons were made in England. Having siad that here is a link to the Waterbury button site showing one identical to your lyre button. Band Uniform - Waterbury Button
I looked through thirteen pages of police buttons on the same site but couldn't find a match for yours. I think the CP button is older than the lyre one maybe around the late 1800s to mid 1900s but that is just my guess.

I know this anchor is relatively modern and was used on children shirts and is a common find. It may be a replica of your 2 hole anchor button. I think youy 2 hole button is modern too. From what I understand 2 hole buttons are considered modern:

Thanks guys. I kind of suspected these to be more modern. Prob 20th century.
The CP button I was also thinking could be older than the Harp/Lyre button, but since the backmarks are so similar, I was thinking probably not much older.
I also felt like the anchor button was probably modern, but in my Warren Tices Record of American Unifor Buttons book I did notice a few 2 hole buttons. So it was worth a shot.
He has some older Flat buttons im going to try to post tonight. I wish I could have posted all of them, but it takes time, and I have been busy.
Thanks for all of your time and help.
