Shewa hour pipe loose

I just found a Shewa regulator clock, that I thought would be a good clock to learn on, to see if I have any aptitude to repair them.

It appears that the hour hand pipe, with snail, etc. moves away from the drive gear, and the hour hand just stops. There is a big spring with forked end that I think is supposed to hold this down but I dont know?

Also the 2 mainsprings scare the heck out of me!!
Anyone ever seen this before?

Also where are good tool and supply dealers close to the space coast?

Thanks, Ed..
