We have a Vintage Speedry Brushpen set out of grandma's estate, trying to get more history on it and possibly a value, includes the pen, eyedropper, box and mostly dried up bottle of ink, the nibs (49) pictured do not fit this pen and they appear not to have been used, although I didn't go thru all of them. I think it is from the late 40's or early 50's, haven't been able to find out much about it. Any help would be appreciated. The box is in pretty good shape for it's age, the eyedropper looks like it is glass and leather or man made and is cracking.
