There is, however, a slight modification to the needle seating, whereby the escape holes are raised slightly to prevent running into the seating. We have instructed modified seatings to be sent to London to replace the 4 you have already received. Hs{Lord Ernest Hives - Chair}/Bwg.{J. C. Bowring} | ||
