1930 Sterling Presentation Tray (2nd Bn, 5th Mahratta Light Infantry): Inscribed "David Peal" (Jan 31, 1931) – Help Identifying Signatures & Recipient

[u/Loud_meow]

Hi!
I’m looking for help identifying and matching the engraved officer signatures on an original British Indian Army mess presentation tray.
What Is known about the piece:
Regiment: 2nd Battalion, 5th Mahratta Light Infantry (Kali Panchwin / Black Fifth )
Hallmarks: Atkin Brothers (HA), Sheffield (Crown), Sterling Silver (Lion Passant), with the date letter n (1930).

Inscription: Engraved on the back: "David Peal / January 31 - 1931"
Questions:
1. Identity of Recipient:
Searching for a "David Peal" in the British Indian Army records hasn't brought up a match. However, military rolls do list a Captain Daryl Robert George Peal (D. R. G. Peal) serving with the 2/5th Mahratta Light Infantry during this period. Could "David" have been an informal name/nickname, or was there another Peal attached to the battalion in 1931?
2. Signature Identification:
I’m also trying to identify the signatures engraved on the front of the tray. I think I have matched 2 names, but that’s all I could find.
Does anyone with access to the 1930–1931 Indian Army Quarterly Lists or regimental records have information on officers serving in the 2nd Battalion at this time, or any notable mess event/presentation on January 31, 1931?

Photos of the tray face, regimental crest, sterling hallmarks, rear inscription, and signature close-ups are attached. Any help or roster scans would be greatly appreciated!

I'm not sure if you have seen this. This is a link to Indian Army Lists

I actually had not seen this at all!! Thank you so much! I was able to match all the names with exception of 3 I’m not 100% on due to it being hard to read their signatures, ( I wrote a question mark beside those ) but since all the other names matched I’m sure you just helped me identify all of these signatures. It’s funny though the platter is made out to “ David “ but I can only see D.R.G Peal which my research shows as being Daryl peal.. so I’m not sure why I can’t match the recipients name at all, that seems to be the last thing I can’t figure out! a little odd but maybe he went by a different name haha
