Re: Is this what I think it is?
What is left of my decal. I have the repro which is of high quality for the Old Dear.Oyster 49 wrote:Great little engines the FVs. The 2 issues are the open water jacket and the screw in leg. The water jacket can cause really bad corrosion of the crankcase, particularly where the studs screw in. Getting the leg out of the water pump housing can be a real devil too.
Here's mine, since the picture was taken I've trimmed the tiller to the correct length and added a correct Dover grip. I think it is now pretty correct v factory spec.
Incidentally the decals are now available, I had a few made, and John now stocks them.
Enjoy!

Boyd if you have one start another topic yeh?
You say three that you may know of......Think again.

Re: Is this what I think it is?
I have been out of Seagull circulation for a bit and so missed this topic unfolding, but I would like to make the following comments:-
1. I suspect, although I am sure Charles P would know, that the Little Model Forty name applies to just the F (40cc) model. It possibly might also refer to the FV, but I do not know. It should be borne in mind that the FV (and the FVP of course) were approx. 55cc.
Certainly the LS model - I think so called because it was a Longer Stroke (LS) version of the FVP and was the first 64cc Seagull. The notation probably generated by the technical/ design staff. In the same way that I have suggested that the SJM/SJP were called that by the technical/design staff because the biggest change over the previous model was to the block. it was now a Sealed Jacket (SJ) rather than the open jacket design of the FVP (and F, FV, LS and LM).
Incidentally, these open jacket block are prone, as has been mentioned to severe corrosion of the aluminium head and aluminium crankcases. I think a lot of instances of corrosion are due to misunderstanding the role of the steel plates at each end, during the inevitable rebuild. These were initially covered with some very durable back goo (I think Charles P might have the details). I believe, that the idea was that these plates, completely covered in this goo were to prevent water getting to the aluminium. Their other role was of course to provide a gas tight seal at both ends. If the aluminium is kept dry, then corrosion will not occur. So just putting gasket goo on the plates where a gas seal is required, does not address the original design spec.
2. There has been some discussion of the numbers of these early series 40s. On my list/data sheet, there are 2 off Fs, 46 off FVs, 31 off FVPs, 46 off LSs and 2 off LMs. These numbers represent a very small proportion of the surviving engines. I will in due course place this list/data sheet on this site, but if anybody wants a copy, I will e mail it to them. However, the recorded numbers, small as they are, have been sufficient to determine/indicate in a lot of cases the probable development of the build standard.

Re: Is this what I think it is?
Good to have back on the site Jeremy.
re the notes on the steel plates in Jeremy's last post; I still have a few available if any one is interested both here and in the UK. also as I still have the cad drawings we can fabricate more if required.

BP,
you were wondering about prices for Seagulls, I got this AD in Melbourne, on ebay, last September for $250. Original owner, second pull start. All I have done is new spark plug (on John W's advice) and the rest is spit and polish and paint.
