Good questions thanks. The only information in the manuals is that they are permanent magnet servos. I find it difficult to beleive that a company like that would confuse resolvers for tachos or encoders. Especially as the same wiring diagram includes the Heidenhain encoder for the main spindle.
This is the view up under the lid of the Z axis motor.

Judging from your photo I would say it's the same as these (Resolvers off of an ebay sale):

hmm, i'm not shure if this resolver will work with todays servo drives.
There is less information in the web about this types. in other boards is written that this old ones have 2 input coils and one output coil, and were driven with an sin and cos signal.
todays resolvers have only on input, and coils for sin/cos output.
don't know if they could be driven backwards, I'm not old enough for such electro/magnetics stuff

I have used Argon drives on a Hurco retrofit, but not sure they had resolver support. It is mentioned that they will in the future, although all that is a bit foggy by now since that was several years back.
They are nice drives, but do have a very irritating issue, namely they use RS485 at very high speeds to program the drives and that link fails as soon as you enable the drive, so use shielded RJ45/STP cable, otherwise .....

Hm. But how are you going to connect your synchros to that?
[edit]
Maybe I'm barking up the wrong tree but your synchro seems to have 3phases at 120° and a "standard" resolver has 2 phases at 90°
