In a previous thread, the group showed a lot of evidence that my Wirt half overlay might be an Aiken Lambert with a Wirt nib and feed. https://www.fountainpennetwork.com/forum/topic/294666-early-paul-e-wirt-eyedropper-filler/ I just found a Wirt MHR taper cap eyedropper with Wirt two line imprint on the barrel (too hard for me to get a good pic of the imprint). It has an incorrect nib and feed. So, assuming they are a good fit, might I be better off putting he Wirt nib and feed in the barrel with the Wirt imprint, and leaving the possible Aiken Lambert to be a somewhat no name taper cap half overlay pen?
