I know exactly what you mean. I’ve been working on my small, but specialized ‘collection’ since 2001. Doing them a piece at-a-time, yourself, is often more meaningful when considering the final outcome of the project.
I wish I had taken on this sooner. I realize that my pistols are the tools needed to get to my rifles. And, I’m slapping myself in the face for not doing this before other expenditures took precedent.
