Here in Spain is also a rare piece, hard to find, but sometimes in the flea market or in antiquaries we can reach some, engraved and with names and dates from that times, 1870's, souvenirs of the Bilbao siege in the carlistas, civil war. The military Museum in Cartagena has a very nice Withworth cannon in excelent condition, thanks to the restoring works of the  Museum friends,wich includes a good number or british guys living in Spain.
