Thumbs up for the last of the Westerly Guilds. The 98 D55 I owned was right up there with the best of them. I also owned a D40 from that period which was excellent.Welcome and you surely pick a good guitar to bring to your introduction. To me the late 90s, 2000, and 2001s - the last of the Westerly's were some great Guilds. Much love here for your D55 and if you have pictures, we love pictures. Post the SN in the mean time and someone will tell you what month and year it was made. Or get a flashlight and shine into the sound hole focused on the neck block - most likely a date there of when headstock was made with guitar being finished 2--3 months after that date.
