Question Impedance of microphones?

[belmontgate]

Apologies if this has been answered before or if inappropriate.
I understand that mikes have high and low impedance, eg moving coil mikes have low impedance and older crystal mikes high.
Whilst I'm still Googling can anyone advise the typical impedance of the following-
1 Crystal mike
2 Condenser mike
3 Moving coil mike ( is this type also called 'dynamic' ?)
The reason for all this is that I'm playing with an old resurrected valved/tubed tape recorder with a long since lost crystal mike. I'd like to replace with one as at 2 or 3 above. Out of sheer cussedness (stinge......) I don't want to use a microphone transformer, for the present at least. I expect the input impedance of the recorder is quite high (ohms ?) and that plugging in a non-crystal mike will give poor performance
I guess I'm asking which of the types 2 or 3 above would most closely match the recorder input, if any?
Also if a small tfr I have would work as a mike trfr. It's an audio or speaker transformer with a ratio of about 120/1
On a related issue, can a mixer such as a mike mixer or a more sophisticated one change input impedance of eg a mike to a different output impedance?
As to why I'm going to all this hassle instead of taking the obvious solution I can only say that due to a perverse curiousity I frequently over complicate simple things
Your patience and any advice much appreciated

If this is a typical tape recorder from the 80's and 90's then it should be safe to assume a condenser mic should do just fine.
A coil mic would then also work, but the record volume may be very low if its impedance is low.

Thanks for the input Globe. Point taken. I'll try and rustle up the highest impedance mike I have around here. I'm sure I have a condenser somewhere and if not they are cheap to buy whereas the only available crystals are old used and expensive for what they are because of interest from the guitar gurus I think.
'Fraid this old beaut has even greyer whiskers! It was bought in 1960 and was useful enough in its day especially with the Aux input connected to the AF stage of a radio for recording concerts etc
