Good Day All;

Can someone please point me to a URL that lists serial numbers and dates of manufacture for Grubb lenses (pillbox type 1850s(?) serial No. 1531). Help very appreciated! :)

Check out the recent thread here (December) on Grubb. This objective is identical to the one I have - my serial number is 1686. This is the Dublin period probably 1858/1859. Patent date is 1857 I think. There is no other info available on line.
