What is it, PLEASE???
Greetings for spring time in Louisiana,
I purchased this "Thing" from a goodwill store. I had no idea what it was and I still have no idea what it is. I took it to a highly regarded gunsmith today. He said he thought it was a part of an aiming device on an artillery cannon or possible a mortar. I realize this has nothing to do with a Luger, but I don't where else to turn. If anyone can shed some light on this "thing", I will be very grateful. It is 8 inches long and 1.25 inches in diameter. I am considering putting it on eBay and let the chips fall where they may. BTW: forgot to mention, no crosshair. Only marking is "B-137188 stamped on the brass part in very small font. Mike |

Hi Ed.
Yes, you can see though it, but not clear at all. Only markings is that number I gave in the post. Mike |

Periscope handle? Just a WAG.

I believe it is an item cobbled together from odds and ends, the workmanship and disparate parts just don't "go together", neither do those strange screws!

I agree with the part of a sub periscope . Bill

Could be part of a theodolite or a transit.

At your next gun show hang it up with a sign "taking offers"......somebody will walk-up and know exactly what it is.......in any case, you will certainly get some lookers and that can't be bad for business............

I agree with Don. This is a home fabrication. There are screws projecting through the serrated part, which makes no sense, and nothing could be threaded onto the end of the black tube because of the thicker flared brass tube. I would add that the shiny bracket on one end resembles a muffler hanger.

Abstract
Based on a recent paper by Rothe and Schäfer on compact binary systems (Rothe and Schäfer 2010 J. Math. Phys. 51 082501), explicit expressions for canonical center and relative coordinates in terms of standard canonical coordinates are derived for spinless objects up to second post-Newtonian (PN) approximation of Einstein's theory of gravity (the third post-Newtonian order expressions are available in the form of supplementary data). The inverse relations, i.e. the dependence of the standard canonical coordinates on the canonical center and relative coordinates, are also given up to the second PN approximation. The famous Pythagorean-theorem-type Lorentz-invariant relation between the system's total energy or Hamiltonian squared, the rest energy or mass squared—solely depending on relative coordinates—and the total linear momentum squared, are explicitly shown through second PN approximation. |

That's a Canardly-Shute prototype night sight for a Matilda tank.

Being an old Submariner the only periscope this could be part of was the one on Jules Vernes Nautilus. Jus sayin
