Help sought re. regiment & approx. date

[pjm007]

Hello.

New member here & first post.

I am looking for help in identifying the regiment of the soldier in the first attached image and getting some idea of the likely date of the image.

He appears to be a bassoonist, and although we can't see it, I believe his sleeve badge is the same as in the second image which is from a different soldier's photo (that one said to be the 50th Foot).

The "badge" appears to include an Irish(?) harp, crown, crossed swords(?) and some form of scroll or ribbon. I haven't been able to ID the badge despite multiple google searches.

Many thanks.
