Old Ale Advice

I brewed 50L of Old Ale last week which has been bubbling away for a week or so on some second gen 1469. OG was 1.078 (lower that I was hoping for due to some efficiency calc cock-ups on my part).

It's down to about 1.028 now and still heading down. I wanted to create something a bit like Emmerson's Old 95 - does anhyone know if this had any Brett in it?
