i have a old feinwerkbau sport 127,in need of tender loving care,i was given it many years ago.it did not have a stock,and it was painted with black paint,i have now got a stock,but the action will not cock,it also needs a new main spring and i suspect a new head seal,whats the best spring to put in,and what could be wrong with the action.any improvements any body could over?
