I wouldn't call Joshua's 'correct' since it comes with wrong caseback, at least judging by his pics...the caseback belongs to 5218-201/A, the original "father" of today's 000 and 005 Logos.
Most of the dealers (DSN excluded) currently offer "close enough" 000 and 005 Logos, the main 'flaws' being G-series dial (L Swiss L) and H-series caseback (H series serial number). Not even many a Paneristi knows the difference between G and H series dial changes on 44mm Luminor Pams, with H & I series having 'L Swiss Made L' under 6 o'clock instead of 'L Swiss L'. Don't expect rep makers to change this anytime soon simple because, well, it sells anyway.
Another "flaw" is the movement that comes in Swiss ETA 000 & 005 Logos from Joshua, Andrew, Ruby etc...it's OPX & OPXI with CDG bridges and SN reg...well that's wrong since gen 000/005 Logos come with much simpler and less decorated OPI and OPII. So far I'm only aware of Davidsen's Logos with the correct mov't inside.
The advantage of 000 & 005 Logo reps should be the simplicity of the movement they house inside, as it's far easier to source and is more affordable to us end-customers....sadly, rep makers seemed to have missed that fact...
Logo reps should be priced in low $200's just like other OPI/OPII based reps (036, 001, 002 etc), instead of late $200's and low $300's simply because they house fancy, wrong and completely unnecessary movement.
