My original compass has had it after 39 years so need to replace. Ritchie makes a ton of different types. Anyone know which one is original to this boat. Want to get a correct fit without drilling new holes, making other mods, etc. This is flush mount in Edson pedestal.
O'Day 28 Ritchie Compass

My O’Day 322 has a Ritchie Power Damp…mounted in the binnacle. I would guess around 4” diameter. I see that the make a 4.5” model….

What is wrong with the old one? The fluid can be refilled if it has an air bubble (see my video below). The plastic spacer that mine sits on had yellowed quite a bit, so I painted it white to match the pedestal. Looks pretty good now…
Here is the refill video…

39 years is pretty good service. I'm pretty sure it's off warantee.
I think the best way to do a part to part swap is to take the old part out, inspect it for any part, model or serial number. Measure it. And the contact the manufacturer to see if there is a drop in replacement.
In today's world, drop in replacements are becoming more rare. I have been amazed at how often I observe buyers of electronics find out that the new stuff doesn't fit the old cutouts. The auto industry standardized radio mounts decades ago. The marine industry hasn't done as well. I once asked a buyer what the reason he bought the chart ploter he did, and his answer was it fit the cut out that existed. He didn't even particularly like the brand.

There are some outfits that will rebuild them.
In fact, Ritchie has a factory rebuild program… Pricey, but way less than a new compass. You need to verify your compass can be remanufactured as they seem to have stopped doing some compasses.

I necked the size of the Ritchie Powerdamp on my O’Day 322, and is about 6” diameter, 20” circumference.
a bit hard to measure In place due to the bubble… and as I look at the Ritchie units, I am not sure what exactly they measure…the entire compass housing or just the “card”.
There are only 3 screws that hold it on the binnacle, so you should be able to remove those, pull the compass and check for an ID tag.

As someone who hates waste, I'd certainly see if it could be salvaged. You can try Viking instruments in Kingston, MA and Dave Witherhill in Cumberland, Maine.
Pulled mine off my 1981 O'Day 34. It's a model SP-5, serial # A81which is a 5" Globemaster. The screw above the label is where oil is put in. Richie sells the oil for it on their site and can supply several smaller seals, but you have to call to get the seals ordered.
I finally took it off. It's an HF-73, no longer made, of course, but my sense is all it needs is a lube job so to speak (fluid refill) and there is a Richie listed service place two towns away so I will give that a go. Hate to scrap it and hate more to start boring new holes.
Adding fluid is not too difficult. I used a child’s medicine syringe to fill mine up. The hole was relatively small.
Odaydokay,
I rebuilt mine last winter. It needed a new lens, main diaphragm and a refill with oil. I ordered all the parts from Vikingcompass.com
Select the Ritchie Compass page and then the ‘Repair Parts’ sub-page. You need to look for the model number on the body of the compass once you remove it from its mounting To get the correct parts. My 1988 O’Day 35 used a ‘Navigator’ DNP-200 (I think that’s the PN).
The only tricky part was getting the last tiny bubble out. It now looks and works like new.
