You're welcome, glad to help out - AND - thanks for thanking.
With the 5" barrel (scarce) and the blued finish (rare - probably because the blued rusted much more quickly and far fewer were made back THEN) your piece is a fine, collectible example - don't see too many in that configuration.
"Bad trigger spring" - ??? - do you mean the trigger does not reset? If it's the main spring (which activates the hammer) it is a DIY project. If it is the trigger return spring - it takes a bit of skill and the correct tools to do the job. 45AUTO (member and contributor) has posted a series of photos (do a search) on trigger guards and trigger mechanisms that have been removed. That job is beyond MY personal poor mechanical skills.
It may be difficult to find a gunsmith willing to work on these OLD guns. Check around your area, ask local gunshops for recommendations - you probably need to find a "old guy" smith to work on it. If it becomes too much of a project - just collect it and enjoy it for what it's worth.
