23 pounds is pretty much average for a mid level mid 80's steel bike. Shed a couple of pounds and you will be in typical "racing" territory (despite most beliefs, most racers weren't weenies when it comes to the weight of their bikes as 21 to 22 pounds seemed to have been the sweet spot for them. 20 and below pounds for steel bikes at that time will be weenie category. anything over 24 pounds was considered heavy by most back then.
Anyway, a pound here and there won't be noticable anyway, so you're in pretty good shape at 23.
