A: wait for S1G to contact you. be patient, he is busy.
have all your serial numbers handy.
does the Series III have a JAP or a BJ engine?
you should be able to get a year date a JAP by its sn from
the info from the JAP websites.
its a letters code.
B: make sure you’ve got all the manuals,
did your machines come with the original books?
always ask about the owner’s manuals when buying a machine,
sometimes they are there, just forgotten.

umm , i see they dont have a JAP manual.
do you already have a JAP manual?
the one thats says “for the engine developed for the Howard Rotary Hoe” ?
there are at least 2 editions.
also absent is a 700 manual.
there are guys that sell good quality reprints too.
C: visit MERL and see what you can find.
their database searching takes a bit of getting used too,
but last time i was there it was easier to use then the first time.
they have a nice collection of all sorts of Howard literature,
i have purchased copies of 2 items not available elsewhere.
unfortunately they claim copyright to the copies they produce,
so i cant put them on the net,
but they are still good info and machine reference documents.
D: of course you have already seen S1G website…”howardgem.webs”
good luck, Rod.
