I have had one for donkeys years , it lives in the garage. I passed it on to my grandson when he was 10 y.o., now he is 20 and has other 'interests' so he gave it me back. It still shoots as hard as the day it left the factory, with just a few drops of oil every once in a while.
Talk about value for money.
I also have the model 25 Centennial, now that is a thing of beauty.
