Hello Southernbelle,
First, I see that you're new, so WELCOME!
I hope that you enjoy Christians Unite. I did try to look some things up on this Bible in a Google Search for "National Comprehensive Family Bible". There is a large number of entries, and most indicate this is an antique, most usually associated with Bibles passed down from generation to generation. Most of the sites I went to had descriptions similar to what you gave, and their primary purpose was to establish values for varying conditions. I would first say that the hundreds of dollars you spent to restore it were worth it. I would do the same thing. We have a very old Bible in our family, so I know what you mean about it being beautiful.
I'm not a collector, so I didn't pay a lot of attention to the values. Most of them were well over $500. If this was mine, I'd never trade it or sell it, mainly because of the exquisite beauty of a hand-crafted Bible. Just reading about how they were made and put together is fascinating.
I think that Geneva would be a good guess. There is a range of time these Bibles were made, and this Bible is very old. The Geneva Bible was very popular before and after the King James Version. The only thing I would know to do is carefully compare Scripture by Scripture between the King James and the Geneva. Most of the very old King James Bibles were prominently labeled as such. In the absence of this prominent label, it's more than likely a Geneva. Regardless, it's GOD'S WORD and a work of art at the same time. People who haven't carefully looked at an old Bible have no idea how beautiful they are. The workmanship was also first class, and they intended this Bible to be passed down from generation to generation.
Love In Christ,
Tom
Thanks be unto God for His unspeakable GIFT, Jesus Christ, our Lord and Saviour Forever!
