Wanted. Rigid A7/A10 Frame

[spanersc]

Hi All. I'm looking to build myself a Rigid bike to use on demonstration runs during a retro week-end. I would much rather use a Twin than the more easily sourced B31/33 single. Anything considered from a bare frame up to a complete bike. In an Ideal world, a later short stroke model would be best but that's probably being a bit hopeful!  Please let me know if you have, or know of anything that would suit.
 Thanks in anticipation. Peter

Morning All.  Still searching for a rigid frame for a twin! I need the later 2 piece frame which I believe will have a 'ZA7' or 'ZA7R' number. Anything would be of interest, damaged, incomplete or even just a rear section. Willing to travel or pay shipping or perhaps meet at one of the UK shows.
Another thought is whether it would be feasible to have a rear section manufactured by a frame builder but I'm thinking the forged brackets could be a problem?  If anyone has such a frame that's accessible, I would really appreciate being able to take some detailed photos for reference (East Anglia area would be nice)
Best Regards,  Peter
