A .22 Mk1 Walnut stocked Vulcan should be landing with me in the next few days. I'll be giving it a service and have serviced a Hawk and Stingray in the past and expect it will be very much like the Hawk to strip.

Am I right in thinking the PTFE piston seal can be swapped out for the later
Webley seal? I'll be looking to have a set of delrin guides made too. Is the Webley factory spring replaceable with a HW95 spring? I'm sure I've read somewhere that you can and that the 95 spring is softer than the Webley spring.
