Submitted evidence
All photographs supplied with this appraisal are reproduced below. Image review is limited to visible surfaces and details.

Photographs cannot establish bore condition, mechanical safety, matching serials, concealed refinishing, internal modifications, authenticity of markings, or provenance. Those factors may materially change value and require hands-on examination by a qualified professional.
A brief history of the Colt Python
Introduced in 1955, the Colt Python was marketed as a premium revolver and became known for its hand-fitted action and distinctive ventilated rib barrel. Production of the classic model ended in 1999, and original blued examples in high condition have become sought-after collector pieces. This example's 1978 production date places it in the heart of the Python's classic era.
