I saw this on eb*y 320733232901 (already ended - I didn't bid)...it looks like a plain magic lantern early petzval....but the 28" inscribed on each ring has me puzzled? Anyone seen it inscribed in that fashion? Doesn't look normal....nor have I seen one in that length, size wise looks to be a 10" FL or so???
Possibly owner inscribed? or maybe not B&L glass, just B&L outer tube...any thoughts
