Hello everyone and this is my first post!

My grandmother had given me this sewing treadle and I can't remember if she had gotten it from her grandmother or if she had bought this at an antique shop.
I can't for the life of me find any info on this machine. Tons of info and pictures on Goodrich "B" and New Goodrich treadles but I have found maybe 2 pictures on the internet of an A model and they were in worse condition than this one.
It is time for me to part with this machine and I am looking for any info as to what it is worth or if it is rare or not.
These may very well be the first good pictures of an A model on the internet! Also has an accessories box.
