Dear Robert,
Thank you for the additional images/ information and your patience.
Sadly regarding technical problems, the images and messages were not displayed. I apologize for the delay of the appraisal.
The presented object appears to be a German Imperial Cavalry sword made by the manufacturer Pack Ohliger & Co, Solingen. The design indicates that this piece was made in the late 19th century or in the early 20th century before the year 1908.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 150 to 300 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.
With kind regards,
Georg
The stamp is OHLIG
