Vintage Machinist Tool Identification & Appraisal Resource Service

The user stumbled upon some old machinist tools, specifically Starrett items, left behind by a previous homeowner and is looking for help to identify them and understand their value. The question "What am I looking at here?" and the follow-up comments about resale highlight a common need for accessible information and valuation for such finds. A resource like a "Comprehensive Illustrated Guide to Vintage Machinist Tools" (available in digital or print) would be incredibly useful. This guide could cover major brands like Starrett, Brown & Sharpe, and others, with detailed identification points and current market value ranges. Selling this guide for around $20-$50 per copy could generate revenue. Alternatively, a "Vintage Tool Appraisal Service" where users can submit photos and details for expert review and receive an identification and valuation report for a fee would cater to those seeking direct expert assistance. Revenue would come from appraisal service fees, ranging from $30-$75 per appraisal based on complexity.
