Check with the guys at the Civil Defence Museum website. They documented step by step restoration of their thunderbolt. I have a mid seventies install manual for a t-bolt. The only pallet specs in it are for the pole mount and the flat roof mat. If you want them let me know. The post above yours is...

I'm surpised the caller doesn't have to use a passphrase to finish activating the siren(s). It sounded as though the siren controller used caller ID to only allow certain numbers to call and activate. So, if a siren controller with an unlisted siren number could only accept a call from phone number...

The shipper will help you with the paperwork for bringing the siren into the U.S. There'll be a fee (there's always a fee) but i6t might not be too bad. As others have said, the shipping will be a female dog.

I believe Thunderbolt horns were made by wrapping sections of sheet metal around a form or mandrel. You can see the seams between the sections when you look at a horn. Heck, you can see them in the horn at the top of this page here. Guess? that damage is along a seam between sections of the horn. Si...

Austin, Thanks for the picture, but just one question: 51 Av? 48A St? In Leduc, Alberta? Where is 1 Ave? OTOH, I'd love to visit the town.

They also won't care because you'll have to give them a certificate of insurance showing that they are an "additional insured," which means that you have to defend them and pay any liabilities arising from what you do. Your insurance covers their exposure, in other words. The erector/disma...

The shipping would be murder. I can't see importing them as making financial sense.

I don't know how you got a price that cheap for the crane, but you're going to have to have a crane with a jib to get that much reach.
