Pattern '18 objective (OG) lenses

[Peter Laidler]

I am just about to have some OG lenses made for the PPCo Pattern 18 telescope made. Anyone need one? To replace that old chipped and scratched one that you can't see out of perhaps...........

As per usual, they will be made in the UK......., no foreign rubbish here..... and to the exact spec as the originals too.
