[John Letney]

Shakespeare Model 4291-2 eye protector for AT-1729, 4242-MK series and 4243 antennas http://www.shakespeare-military.com/milantennashow.asp?product=4291-2 .
 Or  the Model 4291-1 for the model 120 antenna  http://www.shakespeare-military.com/milantennashow.asp?product=4291-1

Which is the “small one” SC-C-446046 5985-00-930-7223 and which one is the “large one” SC-C-446180 5820-00-437-2553? Need to know as a lot of eBay items and catalogs only show them as small or large?

Thanks
