I bought a pinscore display set for my williams Black Knight. No problems installing and they are running fine.
That is until I saw videos on you tube showing the original gas display tubes. As it turns out Pinscore made the design decision to omit the small "tails" on number 6 and number 9.
I contacted pinscore through marco specialities and they confirmed that it was a concious decision to leave out the "tails". The product is still of good quality but purist may still be warned that this minor detail is different from the original gas display tubes.
Just wanted to let you all know.
