Full arc: Russian & German 37 mm AT guns?
Restricted arc: British 2 pdr (despite being a 360 degree mount)

restricted arc: Russian 45mm AT gun?

Also, can any "lumbering" AT gun have a full arc? it's feels a bit contradictory.

Isn't it easier to bin lumbering all together and say that arty over 40mm can only move once (if at all) and give those a restricted arc with a few obvious exceptions?

Yes please scrap that lumbering rubbish  

Maybe just rule as 'can't pack up and setup in the same turn'

Even this is really un-necessary : Three orders to achieve it, not really a common occurence.

Full  arc for a German 37 and then restricted for Russian 45 is really daft. They were essentially the same gun.   

Rather than a blanket "no second move" or "Lumbering" I'd sooner see something like -1 CV for each previous move action. Seems more in keeping with the Warmaster approach - YMMV

I think the BKCII - /5 /10 cm move differentiated between the mobility of various guns pretty well.

Finally, although the German 37mm inspired the Soviet 45mm gun the Russian version was almost twice as heavy, IIRC.
