I am looking for close-up and detail photos of the 0.50 cal M2 mount seen on "Urdan" type cupolas used on the M48. This combination of the Urdan cupola and the .50 cal machine gun seems to be more common outside the US Army; most US M48A5 photos I could find have the M60 7.62mm gun on the Urdan cupola.

Can anyone help? This MG mount seems to be very different from the one used on the M113 and other vehicles. The following photo of a Greek M48A5 MOLF may give you an idea about what I'm looking for:

You probably know this drawing from Squadron "M48 Patton in Action" book I think it's the same as the one fitted to early M48s...



EDIT : this machine gun mount part number is 73648875. You'll find detailed TM drawings and exploded views here :
