Cleobury Mortimer continued their remarkable rise by reaching the final of the Powergen Junior Vase.
Cleobury edged out London Exiles, of Surrey League One, 15-14 in a thrilling semi-final in south-west London.
A late try by flanker Paul Hulland sparked wild celebrations from a sizeable contingent of travelling supporters from Shropshire. The only previous North Midlands club to reach the Vase final was Malvern, who won the competition in 1994.
Flanker Jamie Taylor scored Cleobury's first-half try and fly-half Allan Shields added the conversion and kicked a penalty before Hulland was driven over.
Cleobury captain Paul Harding said: "It will take a while for it to sink in that we have reached a Twickenham final. I don't think we can yet fully appreciate what we have done. The cup run has generated a lot of interest locally and we had some fantastic support today.
"It was almost like having a 16th man on the pitch, with the noise our supporters made when we ran out. They seemed to outnumber the Exiles' supporters three-toone and that was a fantastic lift for us.
"It was another hard game because they were a big and well-organised side, but we defended superbly and it's a fantastic feeling."
Cleobury, formed from a game between two pub teams only 14 years ago, will play Dorking, of Surrey in the final at Twickenham on April 9 (10.30am) after they defeated previous cup winners Leodiensians, of Leeds. ..SUPL:
