Just taken delivery of this one from a recent Southams Auction. The only marking on top is PARKER HALE stamped on top of the right barrel.
From the specifications it is clearly a Model 602, listed by PH at £270.64 in their April 1984 price list (just over £1K in today’s values). Curiously the fore end wood is stamped M104 which would be their side-lock (then £387.60). I suspect that is an error as it seems unlikely that the fore-ends would interchange between side locks and boxlocks.
With 1981 Spanish proofs it shows very little sign of use in the intervening years although someone has fitted a light gathering pipe sight behind the bead.
It seems very well engineered, but is let down somewhat by the dark stock lacquer or varnish that hides the wood grain and seems vulnerable to chipping off.
I am intrigued by the stamps on the base of the chopper lumps. Any thoughts?
