I thought I'd recheck the Short book for some clearer reference to the sourcing of turrets.
Three types used:
Some ausf. A taken straight from the production line, mostly went to the Hitler line.
Then some earlier ausf. D, presumably from reconditioned/battle damaged/ converted stock.
And finally a specially designed turret, the 'Ostwallturm' or 'Ostbefestigung', with a narrower mantlet, cupola replaced by a simple hatch with a single periscope, & roof armour beefed up from 16mm to 65mm.

He then descends into much detail on production figures and manufacturers... c.180 turrets deployed in this way.

Seems just a waste of turrets and mobility to use them in fixed positions.

It isn't when you don't have the fuel needed to power the vehicle supposedto be beneath the turret. Either way, you're done for

The majority of these turrets that saw action in WW2 more than justified their placement, with multiple kills and sometimes large allied formations tied up by them.
As opposed to a waste it seems uncommonly efficient of the Germans to use up these turrets in this way rather than leave 'em rusting in some yard somewhere. When as severely on the defensive as Germany became, mobility can be sacrificed for excellent placement and concealment. They're also, on the whole, a lot cheaper than custom designed Bunker armaments.
The cost effectiveness is underlined by the sheer number of turret emplacements still being built worldwide along Cold war borders postwar, from Greece to Finland, it was still considered worthwhile to recycle 'obsolete' tank turrets into useful emplacements.

Cheers,
Adam.
