Jane Hackworth-Young, great great granddaughter of Timothy Hackworth, said: "We believe people simply assumed at the time that Stephenson had invented the blast pipe.
The letter confirms that Stephenson was still using inefficient bellows to help power his engines more than six months after Hackworth introduced the breakthrough blast pipe technology that paved the way for reliable steam-hauled trains.
Built in 1827, Hackworth's The Royal George locomotive featured a blast pipe and succeeded in saving the Stockton and Darlington Railway more than pounds 500, compared with the cost of horse-drawn trains.
Colin Divall, professor of Railway Studies at York University, said: "Fans of Stephenson have always argued that the replacement of the bellows with the blast pipe, which was a distinguishing feature of Rocket, was George's idea, but this letter seems to cast some doubt on that."
Furthermore, the system offers highpressure air blower with independent and changeable frequency conversion controls and with special design of flue and blast pipe, which guarantees the negative pressure in the tail stock.
"When Timothy Hackworth was working on Stephenson's Puffing Billy at Wylam, Stephenson came round and said 'What's that little man you have in your chimney?' He meant the blast pipe. That was in 1814.
"I'm not totally convinced he wasn't using a blast pipe as well," ventures Colin.
"It's possible he was already using a blast pipe in a supplementary way.

In 2010, two pipeliners, Cody Martin and Joseph Wade, founders of Cadillac Coating Company, Blasting Heating Coating (C3 BHC), had a vision of a safer, more effective and environmentally sound way to sand blast pipe welds.
Calibrating the blast pipe orifice for steam flow rate would allow it to be cut out as steam consumption rises to the maximum the boiler can sustain.
