Recently (6/22/23) a bunch of us flew out to Texas to pick up 3 sirens I had purchased, and 1 that a friend of mine bought.
I bought 2 Sentry 16V1TBs Serial numbers B708 and B709, and a GDC Model 7 Serial number R590642. The Sentry’s are in relatively good shape, with damage sustained during the trip home. Only to the cones and tops, which are on order.
On the way back we picked up a friends STH-10A from Tiffin, Ohio which is a 1994 model.
