Auctions scheduled tonight through next weekend will feature items from several prominent estates and collections.

Two such estates will be featured at Briggs Auction Inc. beginning at 5 p.m. today at its gallery, 1315 Naamans Creek Rd., Boothwyn. Of the sale's 800 lots, 300 come from the estate of Mary Bullock on Elbow Lane in Haverford. They include a Bailey Banks & Biddle tall-case clock that Briggs president John Turner expects to bring $3,000 to $5,000, a mahogany secretary desk expected to sell for $5,000 to $6,000, and a quantity of Chinese export porcelain.

Another 10 lots come from a mansion near Route 252 and Goshen Road in Newtown Square that figured prominently in the news about a decade ago. Included are four mantels (three of wood, one of marble) and two matching chandeliers, all expected to sell for moderate four-figure prices.

Although not advertised as such, the mansion is generally known to be that of John du Pont, whose estate is to be turned into a housing development, and whose furnishings Briggs has been selling off and on for months.

The top item in the sale is a museum-sized oil-on-canvas from another Main Line estate. It is attributed to Claude Lorrain, whose works have been known to sell for $500,000, according to Turner, who expects this painting to sell for $10,000 to $20,000 because of some smoke damage.

Preview is from 9 a.m. to sale time today. For more information, call 610-485-0412.

Next weekend. At 10 a.m. May 12 in Downingtown, Pook & Pook Inc. will start the second session of a two-day sale of furniture, art and accessories with about 90 lots from the collection of Dr. and Mrs. Charles Brimfield of York.

They include a Pennsylvania Queen Anne cherry secretary desk made about 1745 and expected to sell for $15,000 to $20,000, a Philadelphia William and Mary walnut high chest made about 1730 and expected to sell for $8,000 to $12,000, and a New England silk-on-linen needlework sampler done in 1793 and expected to sell for $8,000 to $10,000.

The top item in that session is a Delaware Valley Queen Anne transitional dressing table bearing the label of the well-known cabinetmaker William Savery. It is expected to sell for $100,000 to $125,000.

The 500-lot session also includes several antique weather vanes, notably a circa 1920 copper jumping horse and rider that comes from the Isaac Clothier stables and carriage house in Villanova and was featured in the 1988 Philadelphia Antiques Show. It is expected to sell for $5,000 to $10,000.

The top item in the first session, beginning at 6 p.m. next Friday, is expected to be a Lancaster tall-case clock made about 1810 (presale estimate: $40,000 to $50,000). The 300 lots also include a 7-foot-high German Black Forest carved walnut hat and umbrella stand ($10,000 to $15,000) and a 1927 Austin "teacup car" convertible ($8,000 to $12,000).
