Anyone know what these are?  They are not the typically seen Melz with the perforations.  Thanks

This appears to be a Beijing Chinese military 6sn7 that has been stamped 1578 to make them more valuable.  The plate structure, spacers and bases appear to be identical to the Chinese ones that I have from 70s-80s.  Nice tube but worth about 10 bucks.

Thanks.  I suspect it isn't genuine or wouldn't be so pristine for not a lot of money!

Agreed they're not genuine. I have a bunch of these and they come grey and black, holey and solid plates.
