I had a few Ben Sherman's back in the day and you're right,they were very good quality,can't remember how much they were from memory.
Arthur Blacks were bespoke,much dearer and costed on what you wanted,what you wanted on it and even if you wanted your initials embroidered on it? The quality of Ben Sherman's nowadays is poor and you're better off buying a fake off some market stall as they seem more robust?
Digressing a bit here but I bought my first 'cherry reds' 72ish from Mallinsons in Driff and from memory I'm pretty certain they cost £7.50 (as I had to pay for them myself through potato picking earnings).
You walk into Dr Martens now and they're £150-£200...WTF !!!
