I have several 19 sets and numerous accessories which i need to inventory. 19 sets are all over the place even in the USA. Not at all the situation with the 18 and 48 set. 

A few years back i did get a 19 set antenna connector from a reader of the 'WS No.19' email group. I am very grateful still. BTW, the Mark 3 is so much better for use than the more common Mk 2. I wad also astonished to see how the vario will load up a short wire antenna. 

I read that someone had spanned the pond with a 19 Set. Bravo !
