OWLS HEAD — Stopping in the Owls Head Transportation Museum to see what's new meant that I was looking for something really old — and I wasn't disappointed. This weekend, May 25 and 26, the museum will host its annual Owls Head Spring Antique Auto Show. Gates open to the public at 9 a.m.; exhibitor gates open at 8 a.m. The show will go on rain or shine and a variety of indoor demonstrations and activities are planned in the event of inclement weather.

On my recent visit, two new items adorned the museum and in the restoration shop they were taking a new look at a very old car.

A 1929 Rolls Royce on display at the museum was once owned by film star Clara Bowe and has been in the museum's possession for a time. It was recently moved into the restoration shop, where it was given the once over and pronounced fit. It will be back on display this weekend. The Rolls is an example of the type manufactured in America under the strict guidelines of the Rolls Royce Corporation in England.

The Pride of Wilson is a 1901 self-propelled, steam fire engine and is the only one of its kind remaining in the world. Built by the Manchester Locomotive Works in Manchester, N.H., it was originally placed into service as Engine 4 in Hartford, Conn. Bought at auction in 1935, it was moved to Wilson, Maine, and used on a farm to generate steam.

In 1968 the engine was donated to the Wilson Volunteer Fire Company for the purposes of restoration. Those efforts have been ongoing ever since. The engine came to the museum by way of Andy Swift of Firefly Restorations in Hope. The Pride will be considered a priceless historical artifact when completed.

A Pitcairn PA-7S Sport Mail-wing, NC13158, is a new addition to the museum. The aircraft boasts a remarkable history and is the single surviving example of a PA-7S on the Federal Aviation Association registry. The sleek 250-horsepower plane, which weighs a mere 2,134 pounds empty, is now on display as part of the museum's permanent collection.

The NC13158 was acquired by Stephen Pitcairn in 1979. The aircraft was originally manufactured in June 1930 and sold in 1932 to John Haddock of the Wilkes-Barre, Pa.-based coal company Horizon Coal. The original list price for the aircraft was $9,500. Pitcairn acquired the aircraft in 1979 and it went through a total restoration in 1983, and a full recovering in 2000.

The rare aircraft was donated to the museum by the estate of Stephen Pitcairn following his death in 2008. The acquisition process took nearly two years, and was completed in autumn 2012, according to Owls Head Transportation Museum Aircraft Conservator Karl Erickson.

See all three unique examples of a bygone era this weekend at the Owls Head Transportation Museum. Swift may be on hand this weekend as well to demonstrate the awe-inspiring replica of a steam pump fire engine, Vesuvius. The original Vesuvius was used to fight the Great Boston Fire and the pristine replica truck, also restored by Firefly Restoration, has been on display at the museum.
