Simon:
for new EP cups, contact Captain's. I had several made to original specs -- all that really matters are the threads -- out of plastic. And, they should have plenty left in pnenolic, too.
BillC, out

Thanks Bill Surplus Shed have all the parts but thanks anyway.
I wonder if it will be as good as the Nikon, I think it will be close.

Structurally, close; there was a war on. Optically, not even.

No Allen Bausch and Lomb 7x50's. They are not here yet, but rest assured they will be on as soon as I receive them.

It would be fun to fit the scruffiest mk28 you could find with prostar optics then pass it around at a optics demo day. Ooh the mischief!

I'm not convinced the difference will be that great. But it's been a while since I got the tropical's out so I might start digging this evening.

I understand Bill's caution about glass - I've seen old large-format camera lenses with imperfections, even a ~1/32 inch bubble in the front element of an Aero-Ektar, but nothing that obvious in the few older visual optics I've looked through.
All I can say about the Mk 28 is that a "coated optics" example is nicer for astronomy than the current $100 range Chinese, and pretty good c. 1970s Japanese, center focus models that I can compare it with. The B&L really opens up the Milky Way from a dark site.

My contribution for the day to this thread. I picked up a Swift Holiday Mark II (Bak-4 prisms) a couple of weeks ago via the bay for the paltry sum of $35. Excellent overall condition minus some fungus in the left barrel. I will probably have it cleaned at some point but it isn't affecting the view from what I can tell.
Excellent optical performance in the areas of apparent sharpness, apparent brightness and, of course, field of view. The sweet spot seems good but not great at around 65% of the field of view. More compact than the Swift Sport King circa 1965 that I have on hand with a more neutral color representation.
I took some pics via my cell phone but they certainly don't do the binocular justice.

Nice Swift Frank, looks in mint condition. Are you collecting old Japanese binoculars too?

Yes. Those are my primary interest as they seem the most readily available in the US market and are vastly overlooked by the current roof prism craze. For that I am thankful as there are so many people out there that don't know what they are missing.
A relatively updated list of those models is found on my flickr page linked below.
From the traditional vintage porro list the Sears Discoverers are probably my favorites though each of the ones in my selection have something specific that makes them appealing. More recent, but out of production, porro favorites would be the Nikon WF and Golden Ring 7x35s.

Ahh that is you! I wondered. Your on a very slippery slope now!
You need a Audubon or two to become a true Japanese binocular collector though.

I wonder why they used PART of a roof prism system as a design on the backplate of a Porro-based instriment?

the optical performance is i think pretty good! i paid with postage £15 i also picked up a pair of komz 8x30 binoculars also dated 1982 for £14 with postage and luckily there what i class "a good pair" ie nice build/assembly and selection of parts and well put together/collimated so will be keeping them as well
maybe "82" was a good year for soviet binoculars?

Bill, it would appear that the semi-penta prism diagram is part of KOMZ's logo!

Russian binoculars must be one of the best bargains in used optics,I seem to be a bit of a magnet for them! Sometimes you get a hand signed Q.C certificate stuffed in the stinky leather case,nice touch I have pair of the 7x35 roofs that look like a notarem knock off they are unbelievably light and optically great(better than the notarems)I wonder if they use mirrors instead of prisms?
