Piano, Organ, and Keyboard/3 pianos ages?


Hi Ralph, I´m Pablo from Ciudad Victoria, Tamaulipas, México. (excuse my limited english).
I´m a photographer, and did a photo research about the actual pianos in a Tamaulipas´s small town for a personal work.
I found 8 pianos and I didn´t found in internet the age of 3 of them.

My question is i you can help me to find this pianos ages:
(I´ll be pleased to compensate for your help)

Hastelow & Co.    serial 4864
Rosenkranz   serial 26916
Elburn          serial 18197

Thanks, Pablo

Hi Pablo:

Hastelow: No records. Probably not a manufacturer but a retailer for whom the piano was made.

Rosenkranz: Manufactured in Germany with no records surviving. This piano more than likely came througth Philadelphia, Pennsylvania, USA

Elburn: Made around 1910, made for a retailer in Kansas City, Missouri, USA.

Best we could do I'm afraid.
