Spiro and others.
This was my main task with trying to obtain data from whoever has an SD/P or any post war 102.
By comparing different sets of data it might just be possible to work out what the original parts were for a specific motor type and year.
I'm doing fairly well with most of it, but as always there's some blank spaces that still need filling in along the way. This is where you guys come into this. With your data i can then compare one against a few others and see if there's any specific changes to any particular parts. A bit of a jigsaw puzzle i know, but i'm getting there.
Transom brackets aside, what we tend to see nowadays on a fairly typical SD is the aftermath of various changes. Some of which are out of necessity rather than anything else. Case in point the rather heavy looking angle iron brackets. Keith pointed this out a bit earlier. Try using an SD on your average boat today with a side mount bracket and things turn pretty ugly very quickly.Hence the vast amount of SD's on record at the moment have all manner of later type brackets on them. Unless we happen to stumble across an SD that's still inside its original box (which we have recently) then who knows what's been messed with on some of the motors we see advertised all over.
I would dearly love to show you some pics of what the Type B No.1 & 2 brackets look like, but i'm not entirely sure how much trouble i'd be in afterwards.
The paperwork i have here very clearly states CROWN COPYRIGHT RESERVED, so i'm very reluctant to take a scan of these and post on here. So unless someone else has a picture elsewhere of the real thing, the best we can do for now is describe them as best we can. I've got a photograph somewhere of one of these, but do you think i can find it! Bear with me and i'll look a bit deeper on another computer for it
In time i will try to show some basic specs in picture form for specific years for all the post war 102's. This might help for some of you.
Wartime motors seem to be fairly straight forward with hardly any changes to speak of. Much easier to work out. It's all the stuff that happens after WW2 is where it becomes a mess, but even so there's still some obvious patterns that they all seem to follow.
Just like Keith, i also spend a lot of time searching the net for any traces of hard evidence. Trouble is the quality of the photographs and old films is not that great. Fuzzy, a lot of times out of focus when you try to enlarge the original picture, and this is what i've set my eldest son as a project during a few lunch breaks with some of his mates. To see if he can sharpen up the footage showing what we think might be an SD hard at work ferrying supplies in a small boat, albeit in 1962!
But, it's still not actual wartime footage. Close, but not close enough.
So we keep looking...

I think it is a an early BRitannia Light twin. Hard to tell.
