21cm case length??

[Collector56]

Hello everyone, just picked up a 21cm morser case from an online auction.
When I got home I was horrified to find it is much shorter than standard.
Measures 168mm long, the pitfalls of buying from the internet.
My last hope is you will tell me it is a rare variation (I hope)
Pictured with a standard case in my collection.

Unfortunately not, should be 230 mm.

I saw that in Steve Graham Auctions. I’ve rang him and emailed him before to measure things I wasn’t sure about.

yes official accepted length was 232,0 +/-0,5 mm. The roughing (little grooves) went 80 mm deep inside from the mouth.

Thanks for the replies, looks like I just got a new ashtray.
