Ah, sorry Danny, I clicked on the Vintage Airgun link not "this", did not see colour variation. Do you think it is more desirable to put back the original springs ? I can flatten and grind the broken one. Could put new ones in to increase power, but seems a pity to change it from original.

Yes, I would also definitely put the original springs back if the velocity is OK.
