I finally found the can of lugs I have. I picked this one out as the least worn, it looks like it might even be NOS. If this one will work for you, let me know and PM me your address, I`ll ship it out to you so you can use it as a pattern. I`ll pay the shipping out to you and you can pay the shipping back. I would be interested in a set of these lugs too, depending on the price.DSCN5881.JPGDSCN5882.JPG
PM sent. Thanks.
Attached is a picture of one of the lugs from my 1938 Twin. There's much more wear to it than the one that you have. One interesting difference is your lug does not seem to have the prominent miss-match line on the lower inside face where the halves of the core came together. Most of the Twin lugs that I have seen have this mis-match feature in this area. I'm not sure it is NOS
simply because of the amount of wear in the tip in comparison to what is shown in some of the Standard Twin literature (actual pictures, not the drawings). As noted in my PM however the walls and inner pocket of the lug you have look to be in good condition and will help with reverse engineering the design.
I've also attached a picture of a tractor that I found for sale earlier this year with lugs that look like they don't have much wear all. Unfortunately the seller was not interested in selling any of the lugs separately from the rest of the tractor. I'm going to look at calculating the theoretical "like new" height of the lugs by using the base width and outside surface angle and see if it comes to a logical number, such as 2.5" or 3", etc. The width of the lug tips in the picture look to be 0.25" or so, so I will factor this in as well.
