Update!!
I submitted an inquiry to the RA to which I received an immediate response. They forwarded my email to the NFC department. I received an email from Jonathan Ferguson much quicker than I expected. He was very apologetic as they are unable to allow me to see the collection. They are short staffed the day I planned on visiting the RA and couldn't accommodate me. They were all so responsive and kind. He suggested that I reach to as early as possible prior to my next trip to see if I could view the collection. I'm a bit disappointed but what can you do.
I will try some of the other options offered by the group. Thank you all for the help and suggestions!!
