LBD 150 lamps are larger in diameter then the LBD 140 as fitted to the P type. They were to be found on the NA/NB they are not the same as fitted to the T types.
Thanks for the information on the 150 headlamps. I'm waiting for condition and cost from the seller. I do not need them but if the price is rite I will hold on to them until some one needs them. Gary K
