Staple gun (Farnborough Town Centre GU14)

Hi
A shot in hope that someone might have one of these needing a new life.
I need a long nose staple gun like in photo that uses 140 staples. The one shown is pneumatic but an eclectic one will also do. I have the 140 staples but my normal gun cannot fit in a deep recess of my motorbike seat that I am trying to recover.
Many Thanks for reading.
