Avionics Brs Daylight Protractor No. 8 on 2040-parts.com

I DON'T NOT KNOW ANYTHING ABOUT AVIONICS OR ITS EQUIPMENT, ESPECIALLY THIS PIECE OF EQUIPMENT. I CAN TEST SOME OF THE EQUIPMENT I HAVE, THIS IS ONE THAT CAN NOT TEST. SO DON'T HESITATE TO TELL ME IF ITS OVERPRICED, I GO ONLY WHAT I FIND FROM RESEARCHING ON THE NET AND CALLING / EMAILING AIRCRAFT PARTS COMPANY'S FOR THERE PRICE'S AND ADJUST MY PRICE ACCORDINGLY.... I CAN NOT FIND ANYTHING ON THE NET AS TO ITS VALUE, SO I AM GOING TO ACCESS A VALUE BASED ON WHAT I HAVE BEEN LISTING. IF THERE IS SOMEONE OUT THERE WHO HAS A VALUE FOR IT, I WOULD LIKE TO KNOW SO I CAN ADJUST THE LISTING PRICE ACCORDINGLY . SO WHAT YOUR SEEING IN THIS DESCRIPTION IS WHAT INFORMATION I FOUND ON THE NET.. I BOUGHT THIS ITEM AT AN AIRCRAFT AUCTION, IT CAME FROM THERE PARTS ROOM, ALONG WITH ELECTRONIC ITEMS, YOU ARE BUYING THIS WITH NO GUARANTEE'S, WARRANTIES, AND NO RETURNS EXPRESSED OF IMPLIED. THERE WILL BE A MATERIAL AND HANDLING FEE OF $10 ADDED TO THE FINAL PRICE TO COVER EXPENSES. ALSO, THE PACKAGE THAT THIS WILL E ARRIVING IN MAY DIFFER FROM WHATS LISTED AS I DO NOT PACKAGE ANYTHING UNTIL THERE IS A BID, THEN AND ONLY THEN, WILL THERE BE A MORE ACCURATE ESTIMATE UPDATED. SO WHAT YOU SEE FOR SHIPPING ARE ONLY ESTIMATES. BRS sky component protractor for glazing at 60 degree slope and CIE overcast sky
