There's a similar Daisy & Fern tumbler in Heacock & Gamble Book 9, 1987, item 306 p.101, which is described (p.47) as a reproduction by Fenton for L.G. Wright. The authors note that the pattern was "massively reproduced" to the extent that "many collectors of old glass shy away from the pattern".
If you believe it to be original Northwood, you might find it useful to get it authenticated by CMoG or WVMAG, not forgetting that WVMAG is completely privately funded, so a contribution to their costs in processing your request would be considerate and warmly welcomed.
