Paul--

No, I do not have the cowl. The plans I have for the actual cowl are
very faded (the plans are over 45 years old) and much of the detail for
the interior is missing; however, it drawn on a 1:1 scale and the
distance from the firewall to the prop flange seems to be 33.75". From
the top, (approx. 29" from firewall) the cowl does not narrow until the
nosebowl, at this juncture it appears to be 32" across--give or take.
The attached are PDF files of the "general arrangement" on a scale of
1:10 and all dimensions are given in inches.

If you need more info, I will dig up as much as I can.

OK Tom I 'll go with what I got so far.
