The Scottish entrepreneur, the premium gunmaker and the Turkish concrete firm

It's pretty quiet in the London market during the dog days of August, so I thought I would inform loyal readers about this little deal I stumbled across that involves the reclusive entrepreneur Dr Jim Hay, who heads one of Scotland's wealthiest families.

For readers unfamiliar with Dr Hay, he worked at BP for almost 30 years before founding JMH Group, a construction and lifestyle company whose upmarket brands include Saville Row taylor Bernard Weatherill, gunmaker Ray Ward and French hunting lodge Parc de Launay.

Dr Hay is also well-known in society for owning Harold MacMillan's old West Sussex pile, Birch Grove.  

Anyway, enough about Dr Hay. Here's the skinny on what's happening at JMH Group. I understand Fosroc - the construction chemicals division of JMH Group that Dr Hay bought out of BP in 2002 for $40 million - has just purchased Turkish cement additives company Idea Kimya.

The deal will take Fosroc's sales well above $500 million mark as Idea Kimya itself is believed to generate sales of about $20 million.

And with annual sales just over the $500 million mark, Fosroc - whose products are being used on projects such as the Riyadh metro, the Oasis Tower in Mumbai and Istanbul airport - is likely to be hitting the radar of some of the city's big private equity firms.

So, watch this space.
