I have an old STANLEY NO. 2513 HB level that im trying to identify year range of manufacture.  No I don't want to sell.  It was my grandfathers.  He was a carpenter in the mid to early 1900's.  It has brass corners and end caps.  Black etched logo.  Made in U.S.A.  no other markings i can identify

Welcome! 

 

Could you post a picture?

Possible clues to help narrow down the date:

"Made in USA" stamp: According to tool collectors, this marking was added to Stanley tools after 1930. The presence of this stamp suggests a later production date than levels without it.

Patent dates: Some antique Stanley levels have a patent date cast into the face. For some No. 25 levels, a patent date might indicate a manufacturing window between approximately 1895 and 1905. While the model number 2513HB specifically points to the early 20th century, a patent stamp could offer more precise information.

"Stanley Rule & Level Co." markings: The company's marking on the tool can help date it. Stanley changed its name and markings over the years.

Online resources: Tool forums and collector websites show examples of the Stanley No. 2513HB, frequently listing them as early 20th-century models.

Thanks Lew!

Welcome @PaulB to The Patriot Woodworker. Glad you found us and came aboard.

 

As Lew asked, picture(s) of the level especially with any unique detail(s) or markings would be helpful.

 

Perhaps @John Moodywill stop by with some additional insight.
