I have decided to sell my remaining Reinhold Krieger designed 1:3.5 scale De Havilland Gypsy Major engine castings. This is eBay item 256719913071, link https://www.ebay.co.uk/itm/257491053600  Initial bid is set to GBP849 with no reserve, end date is Thursday 14th May at 19:05 BST.

I do not have drawings available for this kit unfortunately as I sold them with the previous castings but I will try to make second generation drawings available.  I hope, but do not guarantee, they are adequate.  Sorry but there it is.

Auction blurb follows, for pix see the eBay item:

You are looking at a set of Castings for a 1:3.5 scale De Havilland Gypsy Major I engine in new & unmachined, completely unmolested condition.

NOTE: Pix of the actual castings for sale are up now but there may be more to follow as I will try to put up pix of the 2nd generation drawings (see below) later to help people decide how much use they will be.

NOTE ALSO: that although a couple of pictures are provided of a completed engine for the information of the viewer this auction is solely for the castings set as described below.

The kit comprises the following:

Cast parts: (37 parts)
Crankcase
Housing cover
Gearbox housing
Gearbox housing cover
4 x Cylinder Head
4 x Rocker Arm Cover
4 x Rocker Arm Bearing
Intake Manifold
4 Carburetor Parts
Oil Filter
Oil Chamber with Cover
2 x Ignition Distributor with Cover
Ignition Adjustment Lever
2 parts Oil Pump (Bronze),
2 parts Petrol Pump (Bronze)
4 x Pistons

Moulded parts:
2 parts cooling air duct (black plastic)

I do not have an original set of drawings for this set and the buyer will need to source these separately.  However I may be able to provide 2nd generation drawings but cannot guarantee they will suffice to build the model.  I think they will do but I am not guaranteeing that and the onus is on the buyer to find a set of drawings.  Sorry, but there it is.

The prospective bidder should be aware that only what is pictured will be provided, this is the castings kit I have available.  Once again, the picture of the completed engine is for the information of the bidder only, it is not included as part of the purchase.

A competed example of these engines fetched upwards of ?9k at auction at Christies some time ago so the builder will have a rare item of real value that is close to unique - only a very few of these kits were ever made and fewer built up.  I bought two full sets of castings and sold the other one and the drawings last year.  It's pretty unlikely another set will be auctioned on eBay any time soon, so...

Observant viewers will have seen that this engine is to a larger scale than is common at 1:3.5.  This means that it is quite a big engine.  The specs that follow are from the original supplier and are for information only are not guaranteed to be correct :

I am willing to sell this to the UK,  W. European countries, the USA and Australia + NZ using eBay's Global Shipping program, sorry if you live elsewhere but that's it.
