The final Group 1 race of the year, the $1 million Peters Investments Kingston Town Classic (1800m) has attracted a final field of 16 hopefuls.

The latest pre-barrier draw Kingston Town Classic odds at Ladbrokes.com.au have four single-figure chances led by the Grant & Alana Williams-trained mare Perfect Reflection at $4.40.

Last Perth Summer Racing Carnival the classy daughter of More Than Ready won the race as a three-year-old filly in her fifth win from as many career starts.

She has won just once since when taking out the Group 2 Lee Steere Stakes (1400m) second-up on November 5.

Last time out she ran over the mile at the Ascot track, where she now boasts four wins and two thirds from six starts, and finished third in the Group 1 Railway Stakes (1600m) behind fellow locally-trained winner Scales Of Justice.

Playing God (2010-11) was the last back-to-back Kingston Town Classic winner, while the last mare to win was St Clemens Belle (1999).

If successful in being the next this weekend Perfect Reflection will add to the strong recent record of favourites in the race with six saluting for the punters in the past decade.

Occupying the second line of Kingston Town Classic betting at $5.50 is the aforementioned Railway Stakes winner Scales Of Justice.

Hong Kong hoop Douglas Whyte retains the ride on the Lindsey Smith-trained Not A Single Doubt four-year-old who chases his fourth straight win.

His Railway Stakes win was by a comprehensive two and three-quarter length margin over the defending champion Good Project and this weekend the gelding steps out over further than a mile for the first time.

Out to improve on a sixth in the Railway Stakes stepping out over a more favourable distance and getting the weight advantage is the Allan Sharrock-trained Kiwi raider Kawi.

The multiple Group 1 winner in New Zealand has had two starts at Ascot and Sharrock is confidence the Kingston Town Classic is a more suitable race than the handicap Railway Stakes last time out.

The bookies agree and are keeping Kawi safe in betting at $6.50.

Rounding out the hopes under $10 for the win in the current markets at $8 is Tradesman.

Robert & Todd Harvey saddle-up the Trade Fair five-year-old who has winning form up to 2000m.

He is also a Railway Stakes graduate having run fifth on the back of his third to Perfect Reflection in the Lee Steere Stakes.

Of the double-figure hopefuls the Chris Waller-trained duo of Mackintosh ($10) and Good Project ($11) are the next best fancied.

Waller, who won the race two years ago with Moriarty (2014), also has Vanbrugh ($13) in the mix.
