Patrick, do you know what the original was/should be? If so have a look on The Green Sparkplug Company website, they will show if it is in stock and alternatives.
Cooper Pegler ran a series of adverts in The Fruit Grower magazine each one showed a different item, so far I have not found any syringes but will post details here if I do.
I used that photo on the cover of the April 2012 issue of The Cultivator. It does look as if it might have been 4 wheel drive, unfortunately the photo is not clear enough to be certain.
The Farm Implement & Machinery Review is another great source of vintage adverts and some very good articles, I have about 50 issues in my collection.
Difficult bit with pot maker is getting correct mix of compost material. With someone helping to feed compost in and take completed pots off it could be fairly quick. Always attracts attention at shows, usually with the questions what is it and what does it do. Seeing it in operation fascinates spectators.
The big problem I find with safety goggles, as I also wear glasses, is the reduced clarity of vision having to look through two layers of glass/plastic. But having ruined one pair of glasses by not wearing goggles when grinding I always make sure I wear goggles.
I plan to go through all the copies I have and scan the relevant adverts. In addition to Weeks, there are Cooper & Pegler, Drake & Fletcher, Geo Monro machinery and other products, Auto Culto, Planet, Bristol and Ransomes MG.
Some good photos and an assortment of exhibits. Nice to see another Glem pot maker, I have had one for several years. Not so sure about the ‘Tippings Ltd’ truck and caravan, not what I would call horticultural.
It would be a fair old archive if they did. Not sure when first publication was but with 2 volumes a year and second half of 1934 is volume LXXVIII (78) then the first one could have been 1895.
I will get our editor to put an advert in the April issue of The Cultivator, our club magazine. These are great machines but not many people seem to collect them, possibly due to the weight, about 4 1/2 cwt. If no one takes it on as a project it would be better to see it broken for spares rather than scrapped, just wish I lived a bit nearer.
