There were about 15 employees when I was in service. Now, more or less must be around 15 only.

You can probably write a formal letter asking for gratuity.
Whether Gratuity was mentioned or not is not important.
That company is having financial problems is not relevant to meeting statutory requirements.
Gratuity is never part of salary structure as it is purely a company obligation which they have to meet from their funds or take suitable insurance policy-group gratuity policies.
If they fail to reply complain to the nearest Labour Commissioner under whose jurisdiction the office/factory falls.
They will intervene and assist.
