S400 Carbine + Gary Cane Laminate Stock Valuation

[HW95K]

Hi all,

Just after a bit of help with valuing my .177 S400 for sale. I’ve come back to shooting after a break for a few years, and have found I’ve been enjoying shooting my springer far more than the S400, so I’m hoping to sell it on in order to fund another spring rifle purchase. I’m not sure what the 400 is worth though as I have a lot of custom parts for it. Here’s a link to photos: https://imgur.com/a/mbaWPuQ

- S400 Carbine action - near mint condition, shoots well at roughly 11.5 ish ft/lbs and never had any issues with accuracy or leaking etc.
- Original beech stock - again in great shape just a couple of tiny marks toward the butt end.
- Rowan Engineering bolt, barrel sleeve, set-back trigger and Air stripper.
- Air Arms newer shape filler cap and barrel band
- Logun carbon fiber silencer, very quiet!
- Large Plano hard case
- All the original parts that the above pieces replaced
- Original box and paperwork
- A really nice Gary Cane laminate thumbhole stock with adjustable cheekpiece and butt pad.

Any help figuring out the value is much appreciated.

Thanks
Steve
