Missing the top cone?

That sounds like a old sentry

Looks to me--after freeze framing the vid--as if you've got a custom made housing with an extra-long cone to protect the mechanism. It's definitely an unadulterated 5 HP Federal otherwise.

This is a classic Federal Model 5!

How many ports is this one BTW? The wind up sounds exactly like the Model 5 by my house winds up but when its going steady is has a slightly higher pitch. Listen to that video then listen to mine:

Yeah Your right, It has that higher screeching once it is blowing at full speed... the sentry also has a slower wind up
