Description:   While I do my very best to correctly research and describe the items, especially where antique or vintage items are concerned, I am only human so please regard the photographs as the definitive description and do your own research. If you are unsure about the item, please feel free to contact me via the BobShop platform to answer any questions before bidding, or ask for extra photographs.
Bidding and Payment: Please do not bid on an item unless you intend to complete the transaction, to avoid an SNC being filed.  Please make payment within 24 hours of the item closing, unless by prior arrangement.

Shipping: I cannot be held accountable for the item en-route, but will help where I can. If you do not collect/accept the item/s on delivery and they are returned to me, then then you will be responsible to pay postage again.
