Help dating a Gilbert movement.

Clock movement by Wm. L Gilbert
My father found this movement a few years back, fixed it up (somewhat) and put it in his own home made frame. He's gone now, but I would like some help identifying the type of clock this belongs in.
It has a steel frame (magnetic), "17" stamped in the center below the main hand shaft, "\G\" on the left, and "Wm L GILBERT CLOCK CO, WINSTED CONN, U.S.A" stamped on the right.
There's also a faint "253" stamped on the lower right.
Does anyone have any idea on how old this is, and what the clock frame should really look like?
