Union Picket Boat's Spare Torpedo launching brackets-Questions

[bear]

Hello Building the Picket boat and am at the end of the build and looking for details of the spare torpedo launching brackets. I know that the one's in the MSW's kit are simplified version of the real ones that were used.

 

Are there any drawings or srticles that are of the brackets that where used,and how was the torpedo deployed and set off? I think that somewhere I read about making them over in a build.

 

I have a couple of old prints from newspapers that show side and top down views of the boat and torpedo before and after being deployed. What I want to know about is the front bracket that is shown a the pivot piont for the spare that keeps it down for the deployment of the torpedo under the hull of the ship being attacked.

 

But the print is too small and dark to see how the front guide bracket looks like.

 

Thanks
