Wycherley saddle - any idea of value?

[jill]

Older GP but in very good condition, made by Wycherley of Malpas. It has the flaps that are shaped to go over the knee roll and is in pigskin. Always really well cared for.
A friend still has his wife's after she died several years ago and has asked me to sell it for him. I have no idea what it would be worth, but I will put it on Preloved for him and see how it goes. What do you reckon?

There is one on ebay at £175 and that is probably a realistic sort of price for an older style of saddle.
