So my Halfords Professional Socket Set is about 20 years old now. Unfortunately I lost my 13mm 1/4" inch drive socket 2 weeks ago. Halfords cannot now supply a replacement to buy (only a black one). However searching the internet it has become apparrent that Halfords now sell Halfords Advanced sockets in lieu of the Professional make, (I beleive these Advanced are inferior to the Professional types), is this true. In addition, does anybody know where I can buy a Halfords Pro 13mm 1/4 inch drive socket to complete my set
