Well done on buying and preserving this meter. Whatever you do, please don't strip it for parts! It seems quite a rare beast.
I have three Heathkit VTVMs which use an internal C cell for the ohms ranges. As has been said, yours probably took a No 8 battery. I don't think there are any modern equivalents for the zinc-carbon primary cells used in the No 8, but the "sub-C" rechargeable type might fit. Otherwise, you could try two AAA cells in a suitable tube with spacers.
If you're feeling flush, the Small Battery Company* market a
replica No 8 or 2R10 at a rather expensive price.
* No connection with this supplier other than as a satisfied customer.
