This sale is for a pack of Kadee #19 'Magne-matic' couplings.
Size 17 is described as 'medium', 10.61mm.

I bought these couplings a number of years ago, but have never used them - the pack is still sealed.

I'm also selling a pack of size #17, and one of #18 - see my other current sales.
If you want to buy more than one pack, I'm happy to combine postage.
If you buy them individually, I'll refund the unused postage; alternatively, message me first and I'll amend the sale to suit what you require.

I also have a number of other 00/H0 railway items (mainly French, both freight and passenger vehicles) for sale at the moment - please see my other current sales.
