Hi, I own a low mile 73 Pantera L (sit. in Germany) and would like to replace the original rims with lookalikes preferably made of magnesium. 8" I found with mavric.it, 7" is what I'm looking for. Any help?

I don't know of anyone other than Marvic reproducing a magnesium wheel. Maybe consider the 8" front & 10" rear option which is what Marvic produces the 8" rim for.
Roin Technology makes them in cast aluminum but wider. Finding a repro wheel cast in Magnesium - Marvic as Joules said. Bring your checkbook.
If you don't mind me asking, why would you want to change a pair of 7's with a similar set? Do you just want to spare the originals or some other reason?

Well, mag wheels tend to deteriorate with age and I don't fancy a breaking wheel doing top speed on the Autobahn. So I try to get a brand new replica set.

Yes, understood

Very wise, I always caution those paying $5k for used 10" wheels or $8k a set for wide body Campi's! Marvic wheels are no more expensive, and you have the comfort of knowing they are new.
Reach out to Mavic and get a set of brand new wheels, and peace of mind. And if you want to maintain the original offset/appearance of your wheels and don't want 10's in the rear, just order a set of 4 8" wheels. Replacing the 7's in front with 8's will improve the scrub radius and overall handing, yet be visually indistinguishable.
Herr Hastreng, there's absolutely nothing wrong with running 8" Campy's with stock-sized tires on both front & back. An 8" on the front is a direct bolt-on and eliminates the cheaper 7" wheel's scrub-radius drag, so the steering is lighter. It provides extra brake & cornering traction with a 245-50x 15" tire in front. You retain semi-stock 275-55x 15" rear tires (also a direct bolt-on for 8" Campy wheels). Re-alignment is advisable. I did this in the last century without issues & still have the hard-driven car and the (treated) stock wheels 45yrs later.
As for magnesium wheels degrading over time, this is true: Mag' tends to age-harden and get brittle. The simple fix every 10-or-so years is to dismount the tires off ANY magnesium wheel and place it in your home oven. Bake for 3-4 hrs at 275F- 300F and slow-cool overnight in the oven. Then do the next wheel. This is what the U.S Military did on schedule with magnesium wheels on their fighter planes. It relaxes/anneals internal stresses from age-hardening. Works on vintage open wheel racing mag wheels, too.
If you powder-paint your wheels, it's often applied at 300+F. so its safe. The low stress-relaxing heat also turns stock protective silver paint tan-ish, so after cooling, spray-paint the treated wheels argent-silver again for a stock look. No need to remove the discolored underlayer which is stock zinc chromate showing through. Conversely, I have heard of carefully wrapped, undamaged OEM Campys without tires mounted, cracking while stored on a shelf in a protected garage.
Or buy a set of Roin rims and get the correct 8 and 10" look and save yourself $6K
