Yes, Joe... I know Tiranti. A long established company. Years ago I dealt with them when buying tools and materials for school casting and moulding (sand moulds, aluminium casting). Those days - late 1970s - they had a very full range of goods and a thick catalogue. I imagine their ranges will have reduced due to the trimming of educational budgets plus the far-reaching effects of punitive safety laws.
I think that buying from them should be pretty safe!
