Attached is a snapshot of two outer frame waxes* of the 7 x 21 od 1937-39 frame. Once this is in production others will follow. If anyone has otherwise unusable frames that I could use for dimensions and hole spacing, please pm me.

* For those not familiar with "investment" casting process, a sacrificial wax or plastic image of the part is used, coated with refractory ceramic which is allowed to harden, then the ceramic is fired and the wax or plastic melts and burns out leaving a hard ceramic shell mold. The molten metal is then poured into the mold.

Karl, thank you for the info. I am interested once you get them into production.
I am in no hurry, just collecting all the right parts for when the time comes to put my top together.

BTW, thank you for taking my call and the info for the top iron rivets
