In this unlikely place, and without a flashy sports jacket, a twirling neon sign or even a snappy radio jingle, Bob Paterson has managed to become one of the world's biggest used car dealers.

He is also one of the world's biggest second-hand dealers in trucks bulldozers, iceboxes, and portable toilets. In fact, Patterson admits, gazing modestly at the checkered blue laces in his boot tops, "I can't think of almost anything we don't have for sale - if you want to buy a couple of hundred of them."

Engineer Patterson is employed by the eight oil companies that built the trans-Alaska pipeline. His mission: to sell $800 million in equipment and supplies to the highest bidder. As the consortium's "manager of disposal operation," Patterson is in charge of the biggest private material sale in history. He says he expects to complete the jobs within a year.

To accomplish this Herculean housecleaning, the pipeline owners are staging a series of three -day auctions in a 70-acre lot. Fourteen giant warehouses are crammed with such varied items as dusty "World Cup Football" electric television games, exercycles, 10-foot stacks of Dixie cups, million-dollar pieces of heavy equipment specially designed for contructing the 810-mile pipeline. Oil started moving through the pipeline last June.

When he has finished selling the equipment Patterson will sell the warehouses. "You can fold'em up and haul them away," he said.

In addition to the items for sales here Alyeska Pipeline Service Co.' the formal name of the pipline own-

"We're hoping to sell the camps just as they are, "said Patterson. Some of the pipeline camps, which stretch well above the Arctic Circle and once housed 20,000 workers in the remote Alaskan wilderness, cost up to $20 million each.

Interested buyers - there have been nearly a dozen, according to Patterson - are flown up to the sites for an inspection. The terms for purchasing a pipeline camp, complete down to the ashtrays: Cash on the barrelhead, with delivery of the merchandise open to negotiation.

Last year the oil companies hired a firm of Texas auctioneers to come here and dispose of the pipeline material. In December, when the first sale took place, eight leather-lunged Texans showed up along with about 800 prospective buyers. From all over the United States and some foreign countries, they turned out in 35-below-zero weather and four hours of daylight.

Among buyers so far: brokers for Arab purchasers, a group of Mexican contractor building their own natural gas pipeline, the U.S. government, which was shopping for kitchen equipment, and souvenir hunters.

"The first thing we sold was a 36 inch pipe wrench that cost about $25 to buy new," said patterson. "The guy who brought it paid $100 because he wanted to be first."

One man bought pieces of leftover 48 inch pipe, etched maps of the pipeline on the outside, and is selling them here for more than $100 each. (SECTION) Ofar, hundreds of buyers have put down several million dollars for the pipeline leftovers. Alyeska officials said last week the prices were about 25 percent higher than they had expected.

Parks-Davis, the Richardson, Tex., auctioneers, began sending out notices of the sales to about 30,000 potential customers late last year and taking ads in a number of Alaskan and West Coast newspapers. Since then, sales manager Edward A. Johnson, said, there have been several offers by individuals to buy the entire surplus inventory.

"One fellow flew in from the East Coast with his broker and said he wanted it all," said Johnson. The oil companies turned the man down, saying the bid was too early and they weren't ready.

"You never can tell who has money around here these days," Johnson said. "Some of them are in old dirty work clothes, but when we quote prices that run into the millions they just look at us and tell us they've got as much as they need."

There is still plenty left to buy. Wandering through one of the warehouses, Patterson passed waist-high piles of mosquito netting headdresses, long lines of portable outhouses, racks of Arctic clothing and two small yellow vehicles he said were specially made to scoot along inside the 48-inch pipe.

"At first I was awed at the immense amount of everything we had," Patterson said. "Now I'm still not sure what you do with some of these things. But if there's one thing this job has taught me, it's that there is someone out there who will buy anything you can put on the block. I guess we've even sold iceboxes to Eskimos."
