Another Grote Indiana state police bar

I could not reply to the existing grote bar thread from earlier this year due to insufficient privileges. Not sure why.

But anyway, here's another one. This speaker is quite perplexing. Never seen one of these. It is aluminum. No brand or markings except on cone. Fastened with square U-bolt type things. Anyone know anything about it?

Nice piece! If you received that error, you were likely visiting a threat in the archived area of the site.

The shape of that speaker is very similar, but not identical to, the Motorola TDN6251A.

Nice to see another ISP lightbar. The alley lights are unique, all pics I've found are without alley lights or only with front steady burn.

Trippe Lite used to have that one or a very similar speaker with an aluminum bell 40 years ago, as did Smith & Wesson, and I think maybe even Dietz. I'm guessing Atlas or another speaker manufacturer produced them for rebranding by other companies - very common practice back in the day. I would not be surprised if even Grote sold them.

Based on the other posts about these bars, i think the federal CP is correct for ISP, but i think this speaker compliments the bar well.
