Your best, if not only, bet is to watch for a junker/parts set from which you can strip out the tuner. This might take months or years, but you will eventually find one. In the meantime, you can set this radio aside and attack something easier, like an AA5.
The values of the three tuning sections might not help find a tuner that will physically fit your set. But since this is a tuned-radio-freq (TRF) set, I would expect that the capacitance value of each tuner section will be the same. If you have the means to measure the inductance of the RF coils, then you can compute the required range of capacitance of the tuning caps for resonance across the AM band.

::Hello and thanks to all, My first basket case and I am not starting out well. I got called away , and the tuning capacitor assm. got sold out from under me on e-bay. I'll never let that happen again!The radiola man was kind enough to e-mail me, he says any radiola 44-46-47 21-or22 three gang will work because they all had the same rf stage.Now for the hard part...Where do I start looking? do I need to know the value and manufacturer of such a part? Any sterrage will help! Thanks to all, and no laughing at the newbee! at least where the wife might hear it, please!Also, is a picture of the part a good thing to send to sellers?
:Rob, this is a 1929 model Radioloa, built nearly 80 years ago. Knowing the original manufacturer of the tuner is not likely be too helpful now in 2008. It's like looking for a replacement bumper for a Stutz Bearcat.

::This is one set that can be a real headache. The frame that the stators bolt to are pot metal and usually warped pretty bad. I have had a pair of Radiola 21s over the years and they were too far gone to get working due to misalignment of the tuning capacitors. Unfortunately it is expensive to machine a casting since the cost would be prohibitive. On the upside, I have heard of people getting these sets to work if the warpage is not too severe. The floor model version of your set, the Radiola 46 fortunately is very common. I would keep checking eBay or Craig's List for a junky Radiola 46 and see if the seller would be willing to ship you the chassis and power pack. This may be the most realistic way of getting the parts you need. Radiola 44's seem to be a lot rarer than the floor model 46s. Radiola 46 sets usually go unsold on eBay.

::Rob , Do you know where I could send a pic of the part and get a description that would be useful to the oldradioparts.com site? He has a ton, (by description) And I am not comfortable enough to just shoot for it. And I'm sure that it being a one man business he is pretty swamped, to mess with me..unless I know what I want.But you know what....This is starting to get fun!!!Thanks guys!!I learn alot just reading the site!!!

If you are missing the RF xfmrs too, then you will need those or maybe try to wind your own.
The part you are looking for is a 3-gang tuning cap for a Radiola 44.

::Rob..Doug , I would need a grid dip meter to get the value on the coils correct? also can you help with the description of what I would call this,
