Our family still uses yuntif machzorim (Kawl Bo) that were printed by Hebrew Publishing Company in the 1920s or 30s. We have about 20 sets that my Great Grandfather bought.
Therefore, we always use a separate book for Pesach….and Sukkos and Shavous.
The shul I belonged to years ago in New Haven had these in the Minyan room, but not in the big shul. They passed out of use as most congregants needed something with an English translation and ASrtscroll and others had not yet gone into production of a replacement.
As for shuls, it might be cheap enough for a sthiebel to buy 50 extra siddurim, but I couldn’t imagine a 300 family synagogue doing so.
