Last 18 Size Crescent St With 15 Jewels

[IMHO]

What's the latest serial number seen (watch in hand - not a Waltham list entry!) for a 15 jewel CSt.?

I've got 5,726,355 circa 1891.

Serial numbers 5726773, 5747485 & 6004427 are on the Model 83 poster. Does that count? And, Tom McIntyre once had 6018296.

[IMHO]

I never thought to look there even though the poster is up in my office!

I'd say it counts if you can see that the center jewel is not present.
