Can someone please help me as I have a problem with a Milbro/Diana model 23. The barrel catch is not sprung loaded and seems to be siezed, first of all can someone please tell me if I am correct the barrel catch should be sprung loaded? if it should be how do I release it, I can not see any way in which it is fixed in place.

A picture of the barrel can be seen here.



Many Thanks,
Michael
