I'm pretty sure that most shoe-trees sold by any shoe-maker are the same last. What I mean by that is that if you buy two C&J shoes on different lasts, the shoe trees are the same, not specific to the last.
I never buy trees from C&J, but instead from Bexley - they are significantly cheaper (14.75 Euros) and of better quality (Cedar 3 piece rather than 2) than the C&J ones IMHO.
I was trying to compare apples to apples
For a US customer, as a member mentioned, HGs cost 599. I assume that trees are extra since I have never seen trees included in CJ prices. In comparison to HG's 599 plus trees, you can get MTO Vass (which includes lasted trees) for 700 plus paypal fees
Regarding Asot Shoes, he has listed some new Vass on F last for 495 GBP which is around 100 GBP less than what used to list them at. Plus he can give VAT refund of 20% on the new VAss. I corresponded with for his best price and he quoted 379 GBP plus trees plus shipping. In this case, I assumed around 30 GBP shipping, so 410 total without trees. In comparison, HGs would cost 384 GBP (as mentioned by a member) and to my knowledge the HGs are also without trees.
BTW, Ascot claims to be able to supply shoe trees for Vass.
Solid wood U-LASTED shoe trees are extra at £39.95 + Shipping
I am sounding like Ascot Shoe's spokesperson, but I dont hold his brief. I bought a G&G from him on ebay and it couldnt go through as he was not able to deduct VAT on that and he asked for 76 GBP shipping to India. I declined.
