Yes, it seems that the Colibri would be a good match for sure...then again, with Ridley, you never know
I did some more measuring and the WIN lighter is closer than I thought to the Colibri in the distances (close enough I wouldn't feel comfortable saying which one it might actually be; Colibri is a more famous brand and was in The Man With The Golden Gun, for example, but Blade Runner had a strong Asian influence to the L.A. designs so a Japanese lighter like WIN wouldn't really be out of place either in the movie (I don't think it had a tortoise finish added like mine either way, but given you can only see the top I wasn't too worried about it at $12 when it's the only even CLOSE to the movie lighter I've seen for sale online). If anything, though the movie lighter seems shorter than
either one when I measure the image relative to other parts on the lighter (namely the air vent distance relative to the top chunk above it). There's always the possibility the movie lighter is yet some other unknown brand or a slightly different model from Colibri even (i.e. how many years did they make that design and how much did it vary at the time?) I simply have no way of finding out in 2019 about every single lighter ever made (and I've been looking a lot as I got into lighters). I think either one makes a good display item without knowing for certain. Even replicas aren't always exact, let alone lighters you can only see the top of in a movie.
I do doubt the one in the movie said, "Dolly" on the side either way.
(but I guess it's that hard to find
that model that a collector was willing to take an engraved one anyway).
I bought a Ronson Touch Tip that is engraved, but it's kind of special, having a dozen or so signatures on it during WWII, two of which went on to British Parliament supposedly and the lighter was a wedding gift in 1943 to Walter K. Whigham from the Central Electricity Board. This Whigman fellow had a locomotive engine named after him that broke a record, making the train bearing his name more famous than him. Why or how his wedding gift lighter ended up on eBay is beyond me (estate sale after his death, I would assume). With those signatures, you'd think the historical aspect alone would make it worth keeping by his descendants (unless he gave it away long before for some reason; I've had trouble finding a whole lot of historical information on his life). But either way, the lighter looks like it may have never been used (original wand; no char marks, no paint chips anywhere. Nothing. It sparks, but feels like it could use a bit of oil on the mechanism internally and god knows how old that flint is in it as I doubt it was ever changed if the lighter was never used, but I've gotten used to repairing lighters after collecting over a dozen antique ones). The problem is it's SO nice, as badly as I want to try a Touch Tip out, I don't want to use THIS one in this condition.... I really wanted a Maltese Falcon Touch Tip, but you have to be patient to get one that isn't over $1000 just to gouge collectors (and I mean in less than perfect condition as well). I offered to trade this historical Touch Tip with the guy on another forum that claims to own the original Maltese Falcon movie prop, but oddly he didn't even respond....
