I believe Gration Fernando is worthy of consideration.
I always call him Fernando, although that is in fact his surname. His date of birth is 24/1/1957, and he commenced aikido at Braybrook in March 2014, i.e. aged 57. He is of SriLankan descent. He has trained earnestly and very regularly, and his last grading was to 2nd Kyu at CHD TTC in March 2017.

Since commencing training he has been to 2 Summer Schools (2015 and 2017), 7 TTC courses, 1 Hanami Geiko in Tasmania, and 2 SDTs at Braybrook and St Albans. He is on track for a 1st Kyu test in June 2018, possibly March, as he sometimes does classes at Point Cook or Warrandyte.

In his first year or so he was concerned about rolling and asked me if it was feasible for him to continue with aikido considering his age. I reassured him on this and said I would try and give him special attention in that area. I recall actually mentioning Beverley then by way of precedent. And he has now become competent in rolling.

At his 4th Kyu test he was singled out by Oldman Sensei for a high standard test.

He also found suwari waza difficult, but has applied himself to this very well and is becoming quite comfortable with it, although further work needed. He did successfully grade to 2nd Kyu this year, as proof that his suwari waza is at least satisfactory.

The mountains he is climbing at the moment are the harder slam type backward fall, out of say, a sharp shiho nage, and lowering the body as in the 7 position jo kata or shiho nage from katamenuchi. The difficulty with flexibility at age 62 is apparent, but he is trying earnestly, and I am confident he can achieve shodan in due course.
