hi, i have one that has barnett(over)london, on top of the barrel is a 25 in two different places and what looks like a crown beside each. and under the barrel i found numbers scatterd about, being a 545, just above that is a 19 and on a metal lip is a 54. it also has two names, henry clive
and what looks like bourne with possibly a j in front of that. i know its old but cant find anything that looks like it, it only has 1 band. i coud have been fixed but they done a good job. any idea what i may have
