Condolences. Very nice lot of engines in a fine condition as they are. Do NOT disturb them by pulling them apart.

We could make a reasonable guess to the value of each and every one of them, but I truly feel best value for your Mother would be to eBay them even with the commission involved.

Your pictures are very good of them and would suggest using those same pictures on eBay. Auction off each engine on it's own, start the bidding very low to get the auction moving quickly, over seven days, and be sure to offer them world wide with postage to suit.

Good luck, and be sure to let us know here when they are on eBay, if you decide to choose that way of selling them, with a number etc............I may even bid on one or two that I'm interested in.
