Pentax 77240-A410 Connector Cap/Rubber bottom terminal cap

Thanks to Blincodave, who has identified and purchased said item, this appears to fit any Pentax DSLR body that takes a grip from the K-10D onwards, and (thus, Samsung GX-10, GX-20, K-7, K-5, K-3, and variants thereof - and probably also K-1/K-1 II, although the latter two have yet to be confirmed, and there is no info so far on the KP !)

These caps are apparently not "easily available" in the UK - or even, it seems, in the US! - but he has found a source (see here)!

Thus, as I said there, I'm prepared to consider a "bulk buy" from the US supplier if "anyone" is interested - therefore, if you are interested in buying one (or more?), then please post here and PM me with your details and confirm that - should this go ahead - you will "pay your share"!

BTW: before I do go ahead with any purchase, I will confirm the price-per-cap - including RM signed-for delivery - that will then need to paid!
