Vehicle compliment of telegraph battalion

[ChrisW01]

Good day as the subject says does anyone know the vehicle & horse drawn equipment compliment of a telegraph battalion, specifically No. 5, 6, and 7 telegraph battalions? From a Polish publication (and others) on these three units I've a fair sense of the number of personnel, field phone equipment, cable etc and their movements during the Sept campaign but no idea of wheeled equipment. From http://www.rkd.friko.pl/patrol.html and Forum dyskusyjne - Oglnopolski miesicznik ODKRYWCA they likely used a combination of samochód Polski FIAT 508/518 & cable/equipment trailer and horse drawn wóz telefoniczny wz.37Ł. Does anyone have a better idea of just how much wheeled equipment and what type these or similar units had?

Thanks in advance for your patience.
