I'm looking at a Howard Miller GF clock with a movement identified as 610-220. It needs a suspension spring. Is this a Hermle movement number? There's also a movement number 354030D, pendulum number 280017D. Don't know if those are just HM numbers.

No, it's a Kieninger KSU me thinks.

Those numbers on the white sticker are factory assembly numbers, not very helpful outside the factory loop.

Thanks Willie. Looking at those I believe you are correct. The pendulum hook is not split so I suppose the spring will need to have some sort of hanger instead of that through pin.

The pendulum does not hang directly on the suspension spring. There should be a suspension leader in between the spring and the pendulum. Perhaps laying in the bottom of the clock.

Yeah, I woke up this morning thinking that same thing. It's seems to be missing and the owner says "I think there's a missing part ".⁸ I'll need to find one.

Timesavers has a leader 18734 - would you reckon that would be correct? They also list several springs - I'll measure the remnants of what I have.

That leader (18734) has a hook on the bottom end where yours would need a square hole. Your pendulum already has the hook. You also need to look at the clutch foot to see what should be in the middle of the leader. Double check the case. The original might be in there.

This case has no bottom -- it's open to the floor. That leader's long gone. This leader would need a hole in the center (similar to the 18734) to move the verge. I see what you're saying about the pendulum attachment needing a square hole instead of the hook. I'll keep looking.

It takes the $30 one that tracer just posted. You can get a complete parts movement for that price, so shop around.

Well, now you know what it looks like. I was a bit shocked at the price too. Shop around is good advice.

There are at least two lengths. I think you will need the 6.5" version, but check it out. Willie X

I look on the various auction sites for parts movements and they seem like $$$ ridiculous with crazy shipping fees. I'm not really much of a flea market shopper and haven't seen any affordable donor clocks. This client won't bat an eye at the $30 leader so I'll be probably be getting that one and be done with it.

BFI has em for 14 bucks, or any place that repairs clocks will probably have this leader in their junk pile. It's not an uncommon part.

I try to 'not' support companies that overprice their stuff.
