Mcintosh Stereopticon Co?antique magic lantern lens

I've got many emails wanting to buy these pieces since ending them but when I had them listed before NO-ONE made ONE BID.I am not giving them away to snipers.Since no-one wants to bid I've been forced top list them this way.I am not selling them off-line.All you have to do is make offers and I will review the offers or if you really want it and want the deal closed use the Buy it now feature...It doesnt pay to SNIPE!! I hate listing stuff like this but I feel I have no choice

This is a lens that was found right by the mcintosh stereopyicon but the only name I see on it is "N.Power Co.Inc."on the slide mechanism.There are 2 lenses and one is cracked as seen in photo,other than that it looks very nice.It measures 12" wide by4 3/4" tall and 3 1/4" deep.The lens diameter is 4 1/2" and the knobs are wooden.I will be listing a couple other pieces that may go with this that were found in the old attic next to this apparatus so check those out too.The home that these came out of were of a family that has lived there over 100 years and there great grandfather was big into early scientific and electrical inventions of the day.Sold as is and as seen due to age.Thanks for looking!!!
