Replacement Drive Train Parts

I am soon going to need a set of drive train parts for my bike.
Original equipment is either difficult to find impossible.

42 & 52 T chainrings - I am running a Campagnolo Record or Nuovo Record crank and need some new rings. I think it is called 144 BCD but am not sure.

Regina Oro Chain

Freewheel - English threading, 5 speed: 14, 16, 18, 21, 24T. Heck, even just the cogs would be okay, if they fit a 1st generation Dura Ace or Regina body.

Any optional brands would suffice as long as they are good quality, i.e., Sugino Mighty Comp in lieu of Campagnolo Rings.

I know this reads like a WTB post but I am really after discussion of what my options are. What will fit? What won't? For example, what are my options for a replacement chain; who makes freewheels and cogs; who makes rings in my size that fit?

Another issue - I don't do ebay (too intrusive, no thanks). So, am I stuck buying only from shops?

Boulder Bicycle is my go-to online shop for vintage chain. For a time they were offering bulk chain separately packaged (not factory packaging) for around $15 a chain - Sedisport narrow, for use on 5 or 6 speed FWs. They offer a similar chain currently for around $26.

Check out some of their stuff here: Chains

One thing for sure, buy NOS. No point in buying even a slightly-used chain or FW if they won't play well together.

Be vigilant and keep an eye on Ebay for the FWs; when it comes to Reginas they seem to be fetching all sorts of prices. Personally I'd not spend more than 70 bux shipped. Chainrings? Always been difficult to find in good shape and again prices vary but if you're looking for NOS or barely-used you'll have to bite the bullet and pay a bit. Consumables

The prices on "nice" 144 bcd chain rings are ridiculous.

Been looking for some myself.

^^^^ Goes doubly so for a 42, which is about the smallest 144BCD chainring that can be made.

If we could convince IRD and Soma to make and stock this in 42T, 50T, 52T, we'd be golden.

At $63 the price is competitive with other well-made new chain rings.
