This section of the forum apears to be in need of some activity, so here's a couple of photos of my M100 Special.

Frame - '63 front section, custom rigid rear.
Engine - '53 600, added cranckase vacuum system.
Forks - custom girders.
Tank - early P&M, custom spun brass speedo housing.
Brakes - honda(?) drum rear, suzuki(?) disc front, operted by remote hydraulic master cylinder.
Electrics - custom electric start system, with automated decompressor. custom LED bar end indicators, custom switchgear
Controls - custom levers and throttle twist grip with all cables and wires run inside bars.

All the 'custom' parts were made in my own workshop. The bike has been on the road for 8 years. After some teething troubles with the starter drive, it now performs faultlessly. I managed to heat sieze the engine on the way back from a show last year (hot day and pushing it to 70mph!).
A couple of years ago, I replaced the front disc brake hub with a TLS drum, which is more in keeping with the rest of the bike.
The crankcase vacuum system consists of a reed valve and a large-ish breather directly into the primary case. It creates a partial vacuum in the cases, so anywhere that oil would like to leak out, it sucks air in instead.

Thanks Quinten. I don't know why the photos don't show up - they appeared ok on another post.

The link you used does not end in .jpg, postimage gives quite a few link options, just ensure you pick any of the ones ending .jpg or the forum software does not recognise it.
