Section 61. (When and How the Seller May Rescind the Sale.) (1) An unpaid seller having a right of lien or having stopped the goods in transitu, may rescind the transfer of title and resume the property in the goods, where he expressly reserved the right to do so in case the buyer should make default, or where the buyer has been in default in the payment of the price an unreasonable time. The seller shall not thereafter be liable to the buyer upon the contract to sell or the sale, but may recover from the buyer damages for any loss occasioned by the breach of the contract or the sale.
(2) The transfer of title shall not be held to have been rescinded by an unpaid seller until he has manifested by notice to the buyer or by some other overt act an intention to rescind. It is not necessary that such overt act should be communicated to the buyer, but the giving or failing to give notice to the buyer of the intention to rescind shall be relevant in any issue involving the question whether the buyer has been in default an unreasonable time before the right of rescission was asserted.
Section 62. (Effect of Sale of Goods Subject to Lien or Stoppage in Transitu.) Subject to the provisions of this act, the unpaid seller's right of lien or stoppage in transitu is not affected by any sale, or other disposition of the goods which the buyer may have made, unless the seller has assented thereto.
If, however, a negotiable document of title has been issued for goods, no seller's lien or right of stoppage in transitu shall defeat the right of any purchaser for value in good faith to whom such document has been negotiated, whether such negotiation be prior or subsequent to the notification to the. carrier or other bailee who issued such document, of the seller's claim to a lien or right of stoppage in transitu:
