A rare Grindlay Peerless Jap 500cc "Hundred Model" highlighted lots at the Staffordshire County Showground, UK, on Sunday (October 21).

Brooklands-riden bikes rarely appear at auction

The bike sold for £67,580 ($108,365) through Bonhams, pushing close to its £70,000 high estimate. It is one of only two Hundred Models known to have survived and came with impeccable provenance, having been owned by the prominent VMCC member Edmond "Boy" Tubb.

In 1937, ridden by Tubb, the 500cc machine lapped the famous Brooklands track at over 100mph, securing the "Gold Star" award. It had been on display at the Brooklands Museum since the 1980s.

The most important bike in Titch Allen's long history of motorcycles

Also starring were two Brough Superior SS-80s, which brought a combined £130,000 to the sale. Leading was the ex-CE "Titch" Allen 1930 De Luxe model, otherwise known as Black Bess, which made £68,700. The sale was boosted not only by the bike's rarity, but also by its provenance, having been owned by the founder of the VMCC himself.

The number of SS-80s that remain with the same family since new is very low

A "barn-find" 1925 SS-80 followed, selling comfortably within its £50,000-70,000 estimate at £63,100. An exceedingly rare find, the SS-80 had been with the same family from new - a feature that Bonhams estimates fewer than 10 Brough Superiors can claim. It was accompanied in the sale by its original logbook as well as correspondence between the former owner and company founder, George Brough.

Tomorrow (October 23) will see George Brough's own SS-80, aka Old Bill, sell at another UK auction. The bike is expected to set a new motorcycle auction record with an estimate of £250,000-275,00.
