Were any of these jailbar?

Nope.

I’m guessing that most, if not all of these had A1 blowers?

There are two bolts due East of Houston in a refinery (I personally don't know if they are Houston sirens or not; although they look like it on google earth, same platform and everything). Here are coords for both of them. They are on my Thunderbolts in existence map:

29.74542, -95.16998
29.74266, -95.19964

This makes six Houston bolts left implying they are:
Those Two
Henderson Elementary
Canal St. at Delmar St.
Gazin St. by a pool
Northline Park

Sorry to bump this, but in recent times, some more remaining Houston thunderbolts turned up. These locations include, but are not limited to:

Southmayd Elementary School
Kelso Elementary School
Blodger St. near Ennis
Settegast Park
Kashmere Gardens Elementary School
and lastly, Cimmaron Elementary School.

In typical Houston fashion, they are all the exact same as the aforementioned units, however the blower, controls, and platform are missing from Kelso. Where they went, I frankly have no idea. Also in an interesting turn of events, we uncovered, via. newspapers.com, that the two remaining bolts in the ship channel are most likely jailbars that were installed in late 1952. I do not have the article handy, but I will comb around and see if I can pull it up to post here. Again sorry for the bump but I had some relevant information to contribute.
