When is a restoration worth it?

[railman44]

When is a restoration worth it? Doesnâ??t a restoration (which would mean at least a reblue for the sake of argument) significantly lower the value? I can understand taking a basketcase and investing some money to create a shooter but why would someone take a rare variation and restore it? Obviously, Iâ??m new to this disease â??Lugermaniaâ?� but in the Colt SAA world, very few bat an eye on bluing loss regarding a 100+ year old Colt SAA. I understand with any shooting collectable the finer the condition the more the value but I always equated that to â??originalâ?� condition. Iâ??m also assuming the better or more professional the restoration the less value lost. When would you knowledgeable collectors consider a professional restoration and what percentage of the value would be lost? Hopefully, this is not an impossible question to answer...
