Siemens T-1000 clock oscillator crystal

[Fred55]

I want to change the oscillator clock crystal so I can copy 45 baud
I ordered the proper crystal and have received it, but I don't know where the existing crystal on the board, and which board ?
Can someone help me with the location of the crystal so I can change it ?
still trying to restore the T-1000
Thanks, Fred
