Interesting items from three different estates have added an element of diversity to the event, according to auctioneer Neil O'Brien.

Among items expected to draw attention is a pre-Tasmania era John Glover painting.

Mr O'Brien said the painting, one depicting a European scene, was signed by the painter.

``A lot of his unsigned works are coming up,'' he said.

``We don't doubt that they were done by Glover, but this one is signed, which is always nice.''

He said a gunpowder horn, used by an Irish regiment stationed at Westbury in 1826, and a grand piano were also items of interest.

``Grand pianos tend to sell well,'' he said.

``They don't come up very often, they're mostly upright grands.

``We sold a baby grand piano about a month ago for $3000 _ we're expecting this one to sell for about $6000.''

Mr O'Brien said a number of old maps had also been put up for auction and were expected to be a drawcard for collectors.

The auction will run at Armitage Auctions from 9.30am tomorrow.
