Vintage DD turntables. Are we living dangerously?

Vinyl was too cheap in the 70’s ?
Record dealers drilled sleever and cut corners on the sleeves to mark discounted vinyl, but drilling record labels is something strange, maybe not strange for Japanese ? LOL

Why disc stabilizers are not recommended by SAEC for their Mat ?
Disc stabilizers (record weight) were very popular in the 70’s/80’s

Without record weight drilling is the only way to fix the record to the mat to avoid slippery according to SAEC

I prefer weight on top, no drilling for sure.
I thought SAEC provided that metal bridge to fix the mat to the spindle, i was wrong :( 

SAEC also warned up: they do not recommend to use tape, even thin tape under the mat.

That's actually pretty fascinating overall.

However what I find really odd is that over all the years I have been listening to and perusing LPS in stores etc, that I have never seen one single example with a hole drilled in it for this purpose.

Anybody ever seen one that would align with this information?

So then guys i've bought a second QL10. 
Why?
The first one came from Columbia and useless parcel service trashed it - sadly the guy who sold it packed it like an idiot too.
Wilkinsons in Lancashire did a superb peiece of work over a long period of time to fix it. I got them to put a new PTFE thrust plate and install a silicone nitride ball into the bearing. They recapped it - re-soldered any dry joints and gave it a lengthy electrical 'wet test'. I have now put it into a plinth. I had a local guy polish the platter. Electrically brilliant - the only problem is that UPS managed to smash the cover, break the legs and worst of all damage the platter - its tilted at one end by about a mm - and i am paranoid about a precision instrument (which a turntable is) being slightly out.
I tried to locate a platter and was told to get a machinist to either true my platter or make a new one. If it was to be the latter i guessed it would  easily cost £300 - £500 - it would not have the damping rubber either.
Then along came a QL10 for sale in Glasgow - and I had to have it - with the UA 7045 arm for £400 - fully working. I've sent it directly to Wilkinsons to get it recapped etc - I want it to be 'good as new'.
I must say that the seller bought it about 8 years ago, in a JVC stand, with the top of the line JVC amp for... £25.00 - good man.
@gipsonian - if you are in the UK contact wilkinsons - they know their onions

I will say this. The TT101 and the other Japanese Uber decks may well be a pain to service now - they are complicated - they were back then - they are so now. 
My only question is - is it really worth the bother?
