Afaik they are available, there are certainly plenty of Apex, Bluemels, etc. washers on Ebay. Whether they work or not I can't comment, I don't have enough experience. This was my question to the seller I bought mine from:
I have an old skinny Apex pump. I measure the ID at 14.8mm, I guess I need a 9/16” washer?
and their response:
The Apex skinny pump is normally 5/8 inches (16mm) If you go smaller there will be no pressure. The washers have to be an interference fit.
I swapped it over without cleaning or lubing or anything in a bit of a rush and there is no pressure with the 5/8" although it does seem like it is the right size. I need to have another go at it but would appreciate any advice from anyone with experience in the meantime!

So the Older Apex pump (Grand Prix) looks like a goer. The gold which I thought might have been ano came off with a wipe of meths so it was just some primitive tinted lacquer.
There are no dings or dents which for a 70 year old aluminium pump is pretty good going. I’ll give it a polish, probably not to full bling (though maybe ... 😛).
I need a new washer for it, anyone have any experience? Original is perished- looks like soft rubber, can they be found? I’m guessing there are tons of different bore sizes even if the fixing is standardised.
Or can they be fabricated?
Or will it just be a useless adornment to fill the pump pegs, while the Lezyne road drive goes in the pocket.
