Old Bank account stll has balance 6 years after bankrupcy

I declared myself bankrupt in late 2015, and was discharged 12 months later.
I just discovered that a bank account which was sequestered(?)/frozen by the OR is still showing as having a balance of £300. (Got an email from bank about it, and phoned customer services).

Before I take the day off work to go visit the bank in person (it's in another town), or chase around trying to find out who my OR was, can anybody give me a good guess as to whether I am likely to be able to access the cash?

I didn't have to contribute any of my income towards my debts, nor was any other possessions seized. (I didn't have anything at the time: including a job, other than this cash, which I'd forgotten about).
The OR *was* aware of the account.
