Somebody packed it over the pond from Britain, I do not believe they were ever sold in North America.It is likely quite old and information is scarce

Here is a link that might be useful: Suffolk mowers

didnt realise this was usa based as im in the uk, but thanks for the help.

And I did not look to see where you are based.

Does anyone have any info on how or where to find parts I need a head gasket. I am located in Grimsby, Ontario, Canada. I tried the link to Suffolk Mowers and there just a selection of new mowers, no info on parts.

Generally, the older engines without a dip stick have a threaded fill with possibly a vertical slot in the threads. The correct oil level range would be indicated by the ends of the slot, or if there's no slot, the middle of the threads. Look into getting a vacuum pump to suck the old oil out of it by the fill, because this kind of engine mounting usually makes quite a mess in draining oil. I'll wager that is a sweet-cutting mower, judging by the new ones. In the USA I would buy SAE30HD oil for it - I have no idea what '30 weight' oil is called in the UK. Most engines take 18 to 20 ounces of oil, but you'll find out the first time you fill it. The good thing about the old-style oil fill is it is impossible to overfill it with oil.
