 A Deluxe Space Conqueror mirror would be very close, as would a Criterion 4".

They'd both be 2+" shorter in focal length, though you could just adjust the primary mirror position by sliding the rear cell forward, and possibly adding some spacers to prevent the rear cell full extending, or shortening the length of the rails. The secondary would still be undersized, unless you swapped that out too. Not sure it makes much difference at f/11.5 vs f/12.

Either way, seems a shame to butcher one classic for another, unless you already had the spare mirrors on hand. Certainly wouldn't be cheaper than a recoat, assuming the Eikow isn't scratched past the coatings. 

The thought only occured to me because I could get Chinese 114mm mirrors for $25 or less.

It's an Eikow STH5000.  A rather rare scope.  The entire mirror cell slides down to its full focal length.

That is an awesome scope. Everytime I see that model Eikow I drool.

@Ben H

 

I was looking for the edmund mirror that's been on ebay for months when I wrote that, thinking it might be an option if this one is damaged. It appears to be gone.

This monocular is too cool.  Prototype, perhaps?  EBay.  LINK

Perhaps a ATM made partially from broken old Binoculars that's been stripped of paint and fabric?

If you want to see how this bizarre scope goes together be sure to check out my video: https://youtu.be/6NzubDnX_1Q .

Yes, I had one back in 2012. Very unique scope with its collapsible design but it got passed along in the purge. It actually held collimation quite well and had a 3 eyepiece turret. Been 7 years since I’ve seen another one until now. Here’s a link to mine, it was a ToHo branded one.

They used that scope in  a few episodes of SPACE1999. As a scope and a laser.

It's fairly local to me so I thought I would give it a try. Wish me luck!

I don't think it is a repurposed bino.  Most binocular housings are cast aluminum, not sheet metal.  Additionally, there aren't a bunch of mounting holes for hinges and such.  If it's commercial, it was probably a spotting scope.

 

Whomever made this housing was very skilled in sheet metal work if it's a one-off.

I think it’s a really cool and well made ATM spotting scope. Probably well worth the BIN price. Someone with the skills and know-how to build that would know good optics and not waste time to make such a scope with poor optics. I do think it’s an ATM one-off and not a production proto-type. We know folks had the skills to make things of that quality in the past, we’ve seen plenty of evidence to support that right here over the years. Who knows, it could even be from the ‘Rochester School’, they had people up there who easily had the skills. If I were buying scopes still, I would strongly consider getting it.

The hand-written Japanese? diopter scale might be a clue. A316679 is a part number for an eyepiece retaining ring in the M6B battalion commander telescope, looks like late 40s, early 50s.

Those various and disparate parts add further evidence in my opinion, that it was kludged together from readily available military surplus optical parts in the 1950s or ‘60s by some able home craftsman/ATMer.

Alas Chuck, the link doesn't work for us regular folks.  I can go search for it myself, but thought you might want to know.

Sold by a CN member, he may also have it listed here.  I own one of those and they are amazing telescopes.  A Goto 3" handles like any other 4", they are massive, robust instruments.  The mount is cast iron and the machining is wonderful.  Smooth, precise gearing.  This is one of those telescopes that become a collection centerpiece.
