Anybody know a source of B737 Speed Ref/N1 dual concentric knobs?

Hi- I've looked high and low for these but Knobs.se, flight-facsimile, and simknobs(?) aren't doing knobs any more. These were the only guys I've seen that made the exact correct knob. I've looked at all the usual suppliers I know of (sismo.simparts.de, simworld, etc) and some are close, but not quite spot on.
thanks, dave

Same here, I am now looking at OEM knobs.  Preparing my anus for pricing 

I was going to 3D print some, as they don't really get used a lot but i will see what they cost first.

If you are interested, the Boeing P/N is RD825-101 (Inner) and RC446-147 (outer)

I was fortunate to get some with my ANDERS SWITCHES.  They are just fantastic and I regret I didn't got the rest when available.

Thanks for the replies guys.

The Boeing numbers will be great to have. Thank you. I will research them and see if I can xref them plus see if they are anything EHC makes standard or if it is custom or another mfr. The price- I too am sure would be massive.

I thought I remember Anders made some custom dual concentric encoder hardware? Did he also make the knobs? Is he still around?

Yes, they are EHC Knobs, but a custom part specifically for Boeing.  I have pricing on the Outer knob - $ 90 USD each, i'm assuming inner knob will be the same/slightly less.

Archen is indeed still around, but I think the knobs he was offering with earlier switches were made by Jakob at simknobs.se
As far as I know, he is not making knobs anymore.

Hi Dave,
As mick said the knobs i used was made by Jacob. I hope he will get back someday, they are just perfect! If anyone find them please let me know as lots of customers asks where to find knobs.

Best regards,
Anders

The ACV knobs are resin and the ones from simparts are PLA 3d printing. The ACV knobs are 30 bucks for the EFSI and they fit well to the CP EFIS unit. I have seen very happy customers like Wildcat in Belgium.
I am sure Jacob might be willing to run a production if we have a large order.
Cheers
Luis

Yes let's put some extra "pressure" on Jacob! But seriously, there must be a lot of guys on here that need the correct knobs on that panel so I'm guessing it would be fairly easy to get enough orders together to make it worth one of our craftsmen's time.

Thanks for all the excellent input on this thread and hopefully something will materialize on the radar for these elusive knobs.
