H. A. WEYMANN and SON – History Pt 2: The era of H.W. (Harry) Weymann

Harry W.Weymann

When his father died in 1892 the young 26 year old Harry (H. W. Weymann) energetically expanded the business.

Photo courtesy Tommy’s Guitars, Chicago

I contacted Tommy’s Guitars and they tried to find the original photo but the sale was some time ago and they could not find a better quality photo.  But they do know that the documentation was dated 1899. 

If I could find the now owner of this mandolin it could answer some questions about when H.A. Weymann and Son started serializing instruments, which at present those early years are a bit of a mystery.  So if you bought this mandolin from Tommy’s Guitars, or now own this mandolin, or know who does, please contact me charles@koolaru.com . Many thanks, Charles.) end of update.

The catalyst for this was possibly the buying of production equipment and spare parts from the discontinued S.S. Stewart enterprise in 1898, also of Philadelphia.

Their very early banjos and guitars carried a gold decal, but no serial or style (model) number.  Still later they carried a serial number but no style number. I believe around 1900 they finally added a style number as well.
