Dear Ann,
Thank you for the additional information and your patience. This is instruments or devices for optical experiments regarding light refraction. The instruments are marked with AH LTD and a company with such a name exist in Birmingham Great Britain. It is not clear if this company was the potential producer. These pieces were probably made in the first half of the 20th century.
An estimation would be under 50 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.
With best regards,
Georg
