Hi Fernando
If you have any metal working friends you could re anneal the spring
First heat red hot and let cool slowly in very warm sand over period of few hours, I warm the sand in the oven and then put spring into the tray of sand back into oven and let it all cool down slowly, strictly a job when wives are out of the house.
It will now be soft and you will be able to bend it to desired stretch
Then heat it red hot and quench it in cold water to harden it, it now will be v hard and brittle
Next you heat to a blue colour and quench in oil, whale oil is recommended but I use engine oil
You will find this works perfectly and there is a great satisfaction in getting these old guns back operational
Lovely gun by the way congratulations on a fine acquisition
Regards
Ken
