The coin 10 Rupees Quit India Movement has only one variety listed and the mintage is locked -
1992 B - Mumbai Mint; Proof
I don't know whether this was issued in both proof and non-proof but there is definitely a non-proof variety (which I have in an OGP folder which clearly mentions "Uncirculated set".
So, the following variety needs to be added:
1992 ♦ - Mumbai mint
The 1992 ♦ (non-proof) variety is listed in the other coins of this series:
100 Rupees Quit India Movement
The image below shows the coin with the mintmark that needs to be added:
