I've had two of these Celerys for quite some time. Alas I've never been able to comprehend the lozenge. I thought you had cracked it when I found the matching pictures.
But the three registrations for that date are not for celerys, they are for pomades. Thus, although I want to believe they are De Luca, I remain unconvinced. The 2, and the v on the lozenge seem OK, but the other two, well ??. I have nothing else remotely like them, and they don't look like anything from the major players. The only other lozenge that fits with 2, v, is 2,v,B,3 by Seago & Co on 02/10/1876, no. 303996, but I have no idea if that is for a celery.
