I bought a 97k for £300, advertised as bent cocking link, but gun was built by his brother who worked at company in Birmingham.
So took a chance, a pellet in breach caused cocking arm to fail, £14 to replace.
Looked further, Venom stage 1 internals, Vantage stock, Mach1 brass trigger.
Brother worked for Webley Venom.
Average Spring Gun Shooter
